Issue with opds in 3.1.0

I'm having an issue with the latest 3.1.0 release, where not all of my folders (comics) are displayed when using pods in moon reader+

when I search for the comics I find them and in the webui I see the folders as well. Seems like moon reader+ is only seeing the first page. I have yet to try with another app, but it was fine in v2.

Anyone else having this issue or a fix for this?
