The problem with versioning database

Question

Dear Guru!
1. I created geodatabase with standard tool of arcgis desktop. 
2. Open the Catalog-> Database servers create a connection to the server - created without errors comp_SQLEXPRESS. 
3. Clicked twice - appears geodatabase data -
cuks_gdb (VERSION DBO.DEFAULT)
4. Double clicked on it, I get an error 
Failed to connect to database.
Version not found [DBO.DEFAULT]
Is this normal?
PS. I created a geodatabase using a standart tool "Create enterprise geodatabase" with sde owned schema. It is created with DBO.default version . Should I change the version on SDE.default or even cancel versioning for a while until I figured why not work the service on the layer with feature access.

Run 'Create Enterprise Geodatabase' tool by unchecking 'Sde Owned Schema' checkbox. Sde Owned Schema:
This parameter is only active for SQL Server. Check Sde Owned Schema if you want the geodatabase to be created in the schema of a user named sde. If unchecked, you must be logged in to the SQL Server instance as a user who is dbo in the SQL Server instance, and the geodatabase will be created in the dbo schema in the database.
