I just started a testing instance on my NAS and limited the download to two languages: en, de. It starts up just fine, translates, and then I tried using the correct option.
As soon as I click the “edit” icon within the translated result the focus jumps to the original text. I can then click inside the translation to add my correction but as soon as I start typing the focus jumps right back to the original text supplied for translation.
Has anyone else seen this behaviour?
