Unable to update engine plugin

Summary

I have a plugin installed through the Epic Launcher that I own from Fab. It is a plugin that installs directly to the engine and not something that I add per-project. I am in a discord with the developer and he published an update 5 days ago. Fab even says the plugin was updated on the details panel. However, I do not have the updates and there is no indicator or button to update from the Epic Launcher like the other plugins I have which are per-project based. I know that I get updates, because I have other plugins that have the orange icon and an update button.

I have tried to refresh my fab vault, completely uninstall the plugin and re-install it, remove it from my fab library and add it back, restart my computer, run the epic launcher as admin, etc. but nothing has worked.

Additional Notes

As you can see in the screenshots, it shows another update was even added today (1/4/2025), but I have no updates available in my epic launcher and do not have any of the newly added nodes from updates this past week so I can confirm it is not auto updating
