I think this may actually be because the Scribe badge SQL needs updating to include the subcategories rather than just the parent category. It was noted internally during the Badge review we did the other week, but hasn’t been updated just yet while the Documentation category is going through a little structural revamp. I think that’s pretty stable again now though and I’m hoping to make the changes this week. 
I’ll slide this over to Contribute > Site feedback in the meantime, though if you can replicate the issue of it being a quirk of the Approval queue on your own site then we can always slide it back again.
