Cannot add Developer Products to a place

Any time I try to add a developer product to this place it says “An error occurred while processing your request. Please try again later.” Happens on every browser, on mobile too. I can add them to other games, not this one.

I’m not a web guy, but I’m curious: is this a group place?

Yep. But I can add dev products to other group places in the same group.
