Inability to remove "Tab Group Favorites" from Safari Bookmarks

I'm apparently not alone in having discovered no procedure to durably remove "Tab Group Favorites" from Safari Bookmarks. (See: https://discussions.apple.com/thread/255024473?sortBy=rank)

"Tab Group Favorites" is not only unremovable, any sub folders one has been unwise enough to have created therein are equally unremovable—as far as I'm able to discern—and what's more, their default titles are unrenameable, reverting to "untitled", "untitled 1", "untitled 2", etc. as soon as Safari is closed and restarted.

The inability to durably alter the names of any sub-folders created within "Tab Group Favorites" limits their utility. One admittedly can place bookmarks within these sub-folders, which Safari will retain after shutdown and restart, but one will still have to contend with folders that will, in good time, revert to their default "untitled", denomination.

Admittedly, "Tab Group Favorites" is at the bottom of my Bookmarks, mostly out-of-sight, and easily ignored. All but the most anal-retentive can live with it. The issue of useless, empty, obdurately non-renameable sub-folders hiding under a useless"Tab Group Favorites" folder shouldn't be bothersome. Millions of Chrome users live with an equally unremovable "Other Bookmarks" folder lurking at the end of their "Favorites Bar", so why shouldn't Safari users share a similar annoyance?

But if anyone has wisdom to share that offers relief to my festering, latent OCD, please share.
