-np argument seemingly not working

[brian-odonovan]

I am looking at some very strange alignments and the only explanation I can come up with is that the -np flag isnt working appropriately:

I have the argstring as follows: -k 10 ---ignore-quals --mp 1,1 --sp 1,1 --np 1 --score-min L,0,-0.25

How are the XM and NM tags reported at 105 (should count at mismatches with a penalty -1) but the alignment score is still -33 ??

I personally looked at the alignment for some and they are reported like this:
