Inconsistent variable assignment issue

I am using a piece of code which is working fine in some cases and is not working in some other instances. All I am doing is grep'ing and concatenating.

Below is a working scenario.

Code:
$ echo $var1
REPLYFILENAME=Options_NSE1.txt.enc
 
$ FILE_NM=`echo ${var1##*=}`.gz (Take everything after symbol = from var1 and append .gz)

$ echo $FILE_NM
Options_NSE1.txt.enc.gz

$ echo "File to be ftped is $FILE_NM"
File to be ftped is Options_NSE1.txt.enc.gz

The same code is not working when I have a different value for var1.

Code:
$ echo $var1
REPLYFILENAME=Options_UK1.txt.enc

$ FILE_NM=`echo ${var1##*=}`.gz (Take everything after symbol = from var1 and append .gz)

$ echo $FILE_NM
.gzions_UK1.txt.enc (Incorrectly prints the variable $FILE_NM)

$ echo "File to be ftped is $FILE_NM"
.gze to be ftped is Options_UK1.txt.enc (Puts some garbage .gze in place of the word "File". Prints $FILE_NM correctly, which is different from the o/p of the previous command)

Looks like the echo command is replacing the first 3 characters of what ever it is printing with .gz.Not sure why.

Any help with the above issue is highly appreciated.
