I would report these as maybe bugs but they seem to be around from at least 4.19 and I could not find a bug room…
Anyways this is a bug or a feature or something dunno. When I name stuff like spin boxes it does not always keep the name. It has been around since at 4.19 I am in 4.22 right now and I deleted the box, added a new one with a different name and still… I dunno if it is due to where it is or what but it is weird.
