I clicked the "Upload" button or something like that when you submit a run 3 times... don't ask me why. and now i have Accidently submited 3 runs... is there a way to remove 2 of them ?

Yes, you can. Go to your profile, then "Pending actions" button and in the list of "Runs awaiting verification" click on runs you want to remove. Next to their names will be button, click on it, and "Delete run"

When i click on the run and then the 3 dots next to the name of it - there is only an "Edit Run" button

I can't find the delete button...
