How to Change the TV Library Name in the MacOS TV.app?

I created two TV libraries by option-launching the TV app: the first I changed the name using Sharing preferences to ‘Onboard’ (on the internal SSD of the Mac Studio) and then I created one called ‘Outboard’ on an external disk. I option-relaunch the TV app, and choose the ‘Onboard’ library and, when I go back into Sharing preferences, it’s still saying that ‘Outboard’ is the currently selected library…

surely it should have updated to the name of the currently selected library?

I created two libraries because I wanted to test the responsiveness of having my TV library on a larger, external disk. Although that’s all really rather academic now, seeing as I spent a day reinstalling Monterey onto my Mac Studio, because of the problems I was having with it and now it won’t boot…

Thanks Urquhart, I couldn’t post a reply last night for some reason. However, renaming doesn’t seem to work the way I expect it to… I’m reinstalling the OS at the moment, so will post later…

I’m trying to reinstall as we speak, but it’s telling me that it’s going to take about eighty hours, so I’ll get back to you in a few days…
