Cannot move albums in Galleries folder in the Album Manager

[macstrat]

Self-hosted albums uploaded via FTP are not movable into virtual albums in the album manager.
more detail:
When I upload files via FTP to the Galleries folder and sync, it creates the albums and sub-albums if they are there, but in the album manager, those albums can't be moved.
However, if I use the Java uploader, and it works, uploads the albums and all the images and doesn't error out (thats another issue), I can move those albums into other albums with no issue

EDIT: Updating this with a thread form the piwigo forums on troubleshoot and reproducing the issues on another machine: https://piwigo.org/forum/viewtopic.php?pid=189488
Still having the issue.
