Pictures are glitching between Site 5 and Site 6 of the Gallery

When scrolling down the Gallery, it ends at Site 5. When clicking Next, Load More, or 6, Site 6 opens. Somewhere between Site 5 and Site 6, some pictures disappear.
The pictures eventually come back, but while they are missing, they can only be found by filtering for Engines (at least with GPT-2, this works).
I have observed this several times now. 🙏Please try to investigate what is causing this issue.

ps:
The situation on Site 6 has become even more confusing. The top of the page currently displays the same works from yesterday that just returned from review. However, below them are much newer posts that were published hours later. 🤔
