Hi NightCabbage,
MoiV2 have more options than v1.
Example you can not test option ConstDist in fillet or merge command
I send another file, here you can see exactly one problem.(normal edge near profil edge)
In a complex model is profile edge a strong restriction for using fillet.

filletbu1 ---> nothing work
filletbu2 ---> nothing work with option "ConstDist" radius 2, radius 1 or 3 work, why ???
filletbu3 ---> radius 5, left edge work, reight not
filletbu4 ---> nothing work with option "ConstDist" radius 0,9 and greater
filletbu5 ---> nothing work with option "ConstDist"
filletbu5 and MergeB calculate not correctly with "MergeCommand"

-regards
