In Chrome release 142.0.7444.61 there is a bug that will show the empty value of an autocomplete field as an empty value of the display function instead of none. So like this instead of an empty field:
This has not been an issue for Firefox. It has been solved for Chrome with the 142.0.7444.163 release last tuesday (11th of november). For Edge there has not been a solution yet, so please use a different browser if selecting the empty value to delete is is a problem.
So if you are using an edge browser with version 142.0.3595.53 or 142.0.3595.76 you’ll have to wait on a browser fix.
