I like to be able to switch my equipped armour and weapons (including rings and amulets) with a shortcut key. I have equipment enchanted for various purposes, so when I want to smith, for example, I put on all the equipment that has smithing enhancements via a SkyUI shortcut key. SkyUI initially worked perfectly for this purpose.
Then, all of a sudden, the shortcut keys stopped working as expected. The first group of equipment will be equipped using the F1 key, but when I want to switch to another group of equipment with the defined shortcut key (e.g. F3), my equipped equipment will only be partially replaced by the equipment defined for the F3 group or it won't be replaced at all. I have deleted all groups in SkyUI and redefined them multiple times, but they still won't work properly.
Could there possibly be a problem grouping equipment containing multiple enchantments? The problems started around the same time I got the perk to put two enchantments on my equipment. I did give my enchanted equipment unique names to avoid confusing the mod.
