Reposting here because I realized I put the topic in the wrong subforum previously.

I wanted to update my Closed Shooting 4 to make some balancing, so I loaded the level in my editor, made the changes and uploaded it again with the exact same name as it should be, but every time I try to do that it creates a new file in the workshop. I do know Steam should support updates because there is a change log in every item. How do I solve that?
