Help with gunslinger setup

[hunnidthousand]

First of all thank you for the awesome bot. When I try chaos dungeon with my gunslinger, after casting some skills on handgun it switches to shotgun and instantly back to handgun then either keeps flipping between them or casts 1 skill in handgun but it never casts any skills in shotgun stance. Is there any way I can make gunslinger work decently or is it buggy by nature?

I read other posts about other classes and found out about the GFN mode, enabling it fixed this issue for gunslinger.
