Likely caused by #4341
Latest version, 0.114.1+1.21.4, makes it impossible to shift click to convert all the items into a specific type of block, and instead you have to do them one by one. Has been tested with only fabric api loaded, with loader version 0.16.9.

This will require a bit more thought, since theoretically the stack's count can be checked by a stack-aware ingredient which is why that fix uses the ItemStack.areEqual method as opposed to the ItemStack.areItemsAndComponentsEqual method.

Thanks for the bug report, I have reverted the change that cuased this, 0.114.2 is releasing now to fix this.

Ingredients are not supposed to use the stack's count.
