You can only delete the most recent duplicate. And you need to do this before any other action has taken place (upvote, new translation, comment). If a new action has taken place, you won't see the 'edit translation' button. After pressing that, press the 'Delete' button. You'll get the hang of it eventually. The 'edit translation' button is most handy when you'd like to make a change in a translation that you have submitted.

I guess I'm getting to these notifications too late. Sorry. I'm not seeing any of the options that you describe and now one of the duplicates has your name on it {:-! I'll try to find the other duplicates that I remember from Kapitel IV and maybe I can delete those. Thanks.

You can always delete the second translation if no other action (upvote, new translation, comment) has occurred. Go to the second translation, press ’edlt translation’, then press ’Delete’ and the second translation disappears.

No, I don't get what happened. I've seen this happen today a few times but within the same instant so I thought I must have accidentally clicked the mouse button twice. But now I'm not so sure when I see several hours between them here. Is there a way to delete the duplicate?

Same translation?
