Systemd errors of missing file “No such file or directory” inspite of file being present

The contents of my service file srvtemplate-data-i4-s1.conf is

Code:
[Unit]
Description=test service for users
After=network.target local-fs.target

[Service]
Type=forking
RemainAfterExit=no
PIDFile=/data/i4/srvt.pid
LimitCORE=infinity
EnvironmentFile=%I
.
.
.

[Install]
WantedBy=multi-user.target

I am starting my service as follows passing it an environment file but it fails with error as below.

Code:
# systemctl  start srvtemplate-data-i4-s1.conf@-data-i4-env.service
Failed to start srvtemplate-data-i4-s1.conf@-data-i4-s1-env.service: Unit srvtemplate-data-i4-s1.conf@-data-i4-env.service failed to load: No such file or directory.

The files are actually present
Code:
# ls -lrt /usr/lib/systemd/system/srvt*
-rw-r--r-- 1 root root 815 Dec 13 07:31 /usr/lib/systemd/system/srvtemplate-data-i4-s1.conf@.service

# ls /data/i4/env 
/data/i4/env

# cat /data/i4/env 
SRV_CONF="/data/i4/s1.conf"

But systemd not able to find the files.

When I do systemd reload and then fire the ablove start command it works fine.

Code:
systemctl daemon-reload

But still why is systemd not able to find the files and what can I do so that start command succeeds without firing the reload command?

SYSTEMD-SUSPEND.SERVICE(8)                                    systemd-suspend.service                                   SYSTEMD-SUSPEND.SERVICE(8)

NAME
systemd-suspend.service, systemd-hibernate.service, systemd-hybrid-sleep.service, systemd-suspend-then-hibernate.service, systemd-sleep - System sleep state logic SYNOPSIS
systemd-suspend.service systemd-hibernate.service systemd-hybrid-sleep.service systemd-suspend-then-hibernate.service /lib/systemd/system-sleep DESCRIPTION
systemd-suspend.service is a system service that is pulled in by suspend.target and is responsible for the actual system suspend. Similarly, systemd-hibernate.service is pulled in by hibernate.target to execute the actual hibernation. Finally, systemd-hybrid-sleep.service is pulled in by hybrid-sleep.target to execute hybrid hibernation with system suspend and pulled in by suspend-then-hibernate.target to execute system suspend with a timeout that will activate hibernate later. Immediately before entering system suspend and/or hibernation systemd-suspend.service (and the other mentioned units, respectively) will run all executables in /lib/systemd/system-sleep/ and pass two arguments to them. The first argument will be "pre", the second either "suspend", "hibernate", "hybrid-sleep", or "suspend-then-hibernate" depending on the chosen action. Immediately after leaving system suspend and/or hibernation the same executables are run, but the first argument is now "post". All executables in this directory are executed in parallel, and execution of the action is not continued until all executables have finished. Note that scripts or binaries dropped in /lib/systemd/system-sleep/ are intended for local use only and should be considered hacks. If applications want to react to system suspend/hibernation and resume, they should rather use the Inhibitor interface[1]. Note that systemd-suspend.service, systemd-hibernate.service, and systemd-hybrid-sleep.service systemd-suspend-then-hibernate.service should never be executed directly. Instead, trigger system sleep states with a command such as "systemctl suspend" or similar. Internally, this service will echo a string like "mem" into /sys/power/state, to trigger the actual system suspend. What exactly is written where can be configured in the "[Sleep]" section of /etc/systemd/sleep.conf or a sleep.conf.d file. See systemd-sleep.conf(5). OPTIONS
systemd-sleep understands the following commands: -h, --help Print a short help text and exit. --version Print a short version string and exit. suspend, hibernate, hybrid-sleep, suspend-then-hibernate Suspend, hibernate, suspend then hibernate, or put the system to hybrid sleep. SEE ALSO
