That sounds like you have 2 control layers in the same preset.
EDIT: or it could be related to the bug reported here (ProffieOS7 Style Library Phase 4 (Early Access) - Q & A - #82 by Fett263)
I’m going to have to test out some fixes this weekend, there is something acting up in the Idle Off just need time to get it sorted.
The control layer is what makes the Special Ability run. If you want to use Phase Change and Toggle Idle Off in the same preset. Set those Special Abilities in your main blade.
Then go back and create your Accent style. The library will automatically disable the Control Layer but will keep everything else the same for the Accent.
This prevents you from having more than one Control Layer in the preset. If you add more than one Control Layer style to a preset it will cause conflicts and not work properly.
