I'll bet that $NF contains a trailing carriage return.  If you remove the
carriage return, I'll bet the problem does not occur.

For example:

   $ echo "hello\r" | gawk '{print $NF"goodbye"}'
   goodbye

And it is easily fixed using the sub() function:

   $ echo "hello\r" | gawk '{sub(/\r$/,""); print $NF"goodbye"}'
   hellogoodbye
