Minecraft Version:
1.12
Inventory Tweaks Version:

Setting up multiple configurations like

fighting:
d1 sword
d2 pick

other:
D1 torch
D2 munition

When switching in game it always says Format error: 'config' enabled and i have to press the sort key again for IT to sort. the sorting works but was wondering about it

ok thanks

That not really an error, just a message saying which one it's just loaded.
