Thanks for the reply, now it works fine. I just wanted to report that i and my friend we found a slight bug with the mod.
So when you have 10 toolbelt mod active and you're eating for example can of peas the peas get trasfered to the 9'th slot and if you drag it into your inventory while still eating it duplicates the item. This also works for crafting, so if you would have Forged steel in your 9'th slot and craft ladders it would not use materials from that slot and when you would cancel it you would receive the same amount of steel you did not use to your inventory but not that slot. I just wanted to let you know about this and maybe try to patch it.
Also forgot to mention, when you have those slots taken up and try to use food or medicine it says your either not hungry or not hurt even though you definitely are.
