Backup set cannot be deleted

I have to start from scratch because database problems and even rebuild does tell about different filesets. So I am happy I can re-backup 100 Gigs now.

But there is a problem as well. I tell duplicati to delete the backup set (keep files, but delete database), confirm the process… And the backup set stays there.

It’s Canary which asks me to spend time with it.

It’s gone. Must have been some browser cache related thing. Maybe shift+f5 next time.
