Detecting 41 Marker genes instead of 40?

[JSSaini]

Greetings, I am currently executing the FetchMGs script with the most recent version, and it is displaying a total of 41 markers genes for each genome instead of the expected 40. Can you provide any insights on whether this discrepancy is normal? Thank you.

for i in `ls *.2500.faa | awk 'BEGIN{FS=".2500.faa"}{print $1}'`; do python /home/saini/FetchMGs/fetchmgs/fetchmgs.py -m extraction $i.2500.faa -o $i.2500.FetchMGs -v -i; done
