It's probably that the path to your logical volumes is too long and df decides to move the information you're looking for to the next line. Of course that screws with the column numbering. Add the switch '-P' to df, and it should work fine.
Explanation: -P forces POSIX mode, which basically means that it should behave compatible to the other versions of df out there and put the information for each device on the same line. Not as readable, but better scriptable.

FBB::mlm(3bobcat) OFoldStream manipulator FBB::mlm(3bobcat)
NAME
FBB::mlm - Manipulator modifying left margins of OFoldStream objects
SYNOPSIS
#include <bobcat/ofoldstream> or
#include <bobcat/ofoldstreambuf>
Linking option: -lbobcat
DESCRIPTION
The mlm class implements a manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested
amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the request
then left margin 0 will silently be used.
Depending on the tab-setting of the OFoldStream the inserted value represents the number of blank space characters or the number of
tab-characters that will be added to the left margin.
The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream. If a
line is still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at
the next word inserted into that line (cf., the example section below)
A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.

"left margin -6 changed to 0, active on this line
";
return 0;
