[Fixed?] Tools selected as special keep being added to the pickaxe tag

This happens when launching MCreator, though only once per day for some strange reason, I have no idea what could be causing this, and deleting items manually would become very tedious due to the mod I'm developing having unique tools as its main focus. Is there a solution to this?

Update: This no longer happens; I have no idea what caused it in the first place, would appreciate any insight on what caused it in the first place though.
