Actually, upon further review...

I suspect your problem is with "lajarat_tipus"

This is a char(1) field that you likely are interpreting as null what is
actually a blank/space and so the first when is false as is the second (not
L) and so the else matches.

I do not use char so am not that knowledgable as to its nuances with respect
to padding spaces.
