when the settings is set to icons or both Bars and Icons, doesnt matter what the "Number to Show" bar is set to, it seems to default to 8 buffs (mentioned in discord was brought up he couldnt set to 4, and mine personally was set to 10) but remained 8 would show

Also it'S impossible to change the settings on the target of target buffs/debuffs
