All ADF dataflow stages disappear after publish

Hello,
I made a source for my Dataflow and added several stages to the existing one. I published and Dataflow showed an error with a new source. I tried to delete it, but could not delete it. I published again and all my stages disappeared.

It is not possible to publish data flow like a this, because I will get an error because there is no connected sink. In any case, it should have been publish with all steps.

How to get them back, why did they disappear and what happened?

And so it was before that.

Any ideas how to restore or how i can see steps?
