If the app / tag the template has listed can no longer be downloaded, it gets blacklisted because it can't be installed at all. It's also the reason why the Update Available is listed as being "Not Available"
Since it *appears* to be related to the dark theme or theme engine, probably best to ask in it's support thread, as it's not an issue with Unraid itself.
It sounds like you're booting into the default mode.
Boot into GUI mode from the boot menu (you can select this as default) via Main, Boot Device, Click on Flash, then SYSLINUX Configuration
Install the nVidia driver plugin?
Also, while not much comfort, at least there is very little reason (other than the odd piece of management) for you to actually use the webGUI of Unraid. Pretty much you should be utilizing another system to interact with the GUI.

Bad memory. Your system event log in the bios should have more info beyond Dimm 0, Channel 0
Unraid has a ulimit of unlimited set. The containers *should* inherit that. If they don't, then in the extra parameters you add in --ulimit options

Blame docker itself. They're the ones who allow it and have the system ignore it.
That's what you're missing. There is never any reason to change the listening port in bridge mode within the app. You only ever change the host port.
Post your docker run command. https://forums.unraid.net/topic/57181-docker-faq/?tab=comments#comment-564345
Try one of the ACS override options. I would think that by and large the PCIe's coming off of the CPU instead of the chipset will always wind up in the same group without ACS
