The new edit name pop out is hard to to fill out
Guest can just see the Roman Blank part . Name show up in the lower Latin . were do you edit the name ? Were do you edit the new name?
There's a large blue X to the right of the Suffix section, in the x-Latn section. Clicking that will remove the Latin section completely.
Then scroll up and change "Other" at the top to English.2
According to posts elsewhere, that x-Latn section occurred when a database conversion to allow the expanded set of language templates could not handle certain now invalid templates. I've assumed these should all be edited to get rid of the x-Latn field.
I've always done this by cutting and pasting both sections of the name into the upper field. If you then change the language from Other to one of the other options, then now blank x-Latn field will vanish.
I've never tried to just remove the x-Latn field. Will the name automatically transfer to the upper section? That would certainly save a little time. I'm not currently in a section of family that has this problem so I can't test it.
As for the original question "Where to edit?" All of the editing boxes are scrollable when they get too tall for your screen. The guest does need to scroll in the example given.2
Most of the few I've encountered were already filled in on both or the x-Latn was empty. If you're uncomfortable just x-ing the Latn section closed, you could reverse my process - switching other to English and filling it in (copy/paste the name) and then x the Latin section closed.
The profile is LJGF-RD5 so you don't have to search for it as I did.1
Went back to the section where I was seeing this a lot and found another. You do have to fill in the upper boxes before removing the x-Latn section or the name just vanishes.
