Dtube/Steemit Problems

Hi Guys,
I have a big problem to post Videos on Dtube with my Steemit Account.
If loged in with Steemit and post Videos, there will be dissapeard and hidden, and not found with search.
On left sidebar the Menupoint "my Channel" is also missing, just seen on Contex menu...

If do same with other Account from Dtube there is not any problem and works well.

Whats wrong?
