Two strings are not shown in Danish in Setting->Files & Links.
The strings are translated in the da.json file but as you can see on the image it is not in the app:
“option-new-attachment-location”: “Standard placering for nye vedhæftede filer”,
“option-new-attachment-location-description”: “Hvor nye vedhæftede filer er placeret.”,
I have not tested if any other languages have the same problem with these strings.
