### Additional context

The issue above is caused by src/desktop/kmshell/xml/strings.xml and src/desktop/kmshell/locale/de/strings.xml are not in synch w.r.t. label `S_Button_OnlineSupport` which in locale/de/strings.xml is `Tavultesoft Kundenbetreuung...`.

Quite similar happens with title of the window for downloading a keyboard which is provided by label `S_DownloadKeyboard_Title`:
In src/desktop/kmshell/xml/strings.xml it is defined as `Download Keyboard From keyman.com`. However locale/my/strings.xml defines it as `Tavultesoftကနေ ကီးဘုတ်ကို ဒေါင်းလုဒ်ဆွဲပါ` and hence containing the suspicious substring `Tavultesoft`.
By the way in locale/de/strings.xml `S_DownloadKeyboard_Title` is correctly provided without `Tavultesoft` as T`astatur von keyman.com herunterladen`.

Files containg `Tavultesoft` are:

- src/desktop/kmshell/locale/de/strings.xml
- src/desktop/kmshell/locale/ff-ZA/strings.xml
- src/desktop/kmshell/locale/fr/strings.xml
- src/desktop/kmshell/locale/my/strings.xml
- src/desktop/kmshell/locale/pt-PT/strings.xml
- src/desktop/kmshell/locale/ta/strings.xml
- src/desktop/kmshell/locale/tr/strings.xml
- src/desktop/kmshell/locale/vec/strings.xml

However there might even be labels not containing `Tavultesoft` but anyway not being in synch.
