Yea i agree the specified option percentage set to 100% should remove 100% of the item regardless of the amount in the device. This works with weapons and items i.e. shockwaves etc. With the weapons you can also have it set to weapons, percentage, 100% and it’ll remove every weapon without any weapon in the index slots.
If you want to remove amounts then the options are amount in the device or change the % value so i do think its bugged tbh
