I have a repo on a compatible s3 storage (cubbit), more or less 30GB written on bucket.  
I delete all snapshot from kopiaui and then re-create all snapshots.  
Why now I have almost double space archivied on bucket and there are also files that kopia wrote before snapshot’s deletion?  
Which kopia operation delete them from bucket?

What about _ **–extend-object-locks** _ parameter in maintenance set? How does it work?

I have never used it but this section in the documentation might give you a clue:
