Ich habe folgendes Problem:
Wenn ich einen Auftakt von einem Achtel in 4/4 einfüge, dann verschwindet von Takt 56 dieses Achtel und ich bekomme es nicht mehr zurück.

Das Entfernen vom Doppelstrich oder dem Tonabwechsel macht leider keinen Unterschied.
welcome to the forum.
If you post a screenshot, please make sure, your Signposts are visible. This will enable to point to the solution. I don’t know the German equivalent for Signpost, but you will find the option in the View menu. Signposts are the coloured flags, that you can see at bar-lines and elsewhere.

That way guesswork will be reduced, and at the same time it will help other users, who run into similar situations.
To come back to your first request: where did you want to put an upbeat?

Does your part have more than one voice in this system? You will find that Dorico is very logical with everything you put in (that’s how it’s built), and discovering the logic behind a “mistake” is extremely enlightening.
