Issue in LG column of muts output

[DrK-Lo]

I noticed that one of the new muts files has some values in the LG column as missing, when this wasn’t the case in the first file you gave me.
first file = /work/lotterhos/MVP-Offsets/practice_slim/mypractice/1231094_Rout_muts_full.txt
new muts = /work/lotterhos/MVP-Offsets/mypractice_20210308/slimdir/1231096_Rout_muts_full.txt
