Can't Remove/Change Items from Quick Slots, Requires Ctrl + Click to Drop on Ground

[Eurafrica]

Once you equip an item to one of the extra Z, V, B, slots, you can't remove them by left clicking or left click and drag. The only way to remove items is by ctrl + left clicking which drops the item on the ground.

Using your Quick Slots mod of course.
