Translation to Danish
I wondered why a common instrument such as the bassoon was absent in the instrument list. The explanation is that the english "Basoon" had been translated to "Basun". However, a basoon is called "Fagot" in Danish, whereas the "Basun" is a brass-instrument. The same applies to the contra-version of the basoon which is a "Kontrafagot" in Danish.

I believe this has been fixed since long (and IIRC by me), have you updated the translation? See https://musescore.org/en/handbook/language-settings-and-translation-upd…
Ah, there it is: #75516: Danish translation of Bassoon is Fagot rather than Basun
