Manage library access names are missing

Server Version#:1.43.3.10861
Player Version#:4.160.0

When trying to manage library access for any particular user the library names are not displaying on the library selection screen.

Ive tried accessing these settings on multiple browsers, and directly on the server its self and its the same across the board.

I currently run 2 Plex servers, my main dedicated server and a portable instance on my laptop for travelling. the portable laptop instance doesn’t have this issue, which you can seen the screens. so this issue seems to be specific to my main servers Plex configuration.

Any ideas how to repair this?

Try a different web browser.
Disable browser add-ins.
Compare the local version of the web app with the hosted web app.
