Scarabs stuck in remove-only currency tab

In SSF Standard I have a remove-only currency tab which is empty apart from a stack of scarabs (they look like they are the “old scarabs” which turn into random new scarabs when right clicked).

This stack can’t be moved or interacted with in any way, so I can’t get rid of the tab.

Also I had a bunch of these “old scarabs” in my inventory when I was sorting out other tabs, then I ctrl-clicked them to move them to my fragments tab (via affinity), but they seem to have disappeared when I did this?
