Beautiful work Mike! We’re looking into this right now.
We will report back with more information once we have a better idea of what’s causing seemingly just gallery to have either a delay, or a sync’ing issue. We are able to recreate/see your issue 
I can say with certainty that if Manifold Studio and OpenSea were showing your updates then there are no issues with the token on-chain which is good! At the moment I believe this is a display layer bug on our side with just Gallery.
Big apologies for the inconvenience, I understand how stressful it is to have to list/unlist artworks because the display is off, not fun <3
