Schema list is not refreshed when creating a new schema

Go to a studio project
Create a document type
Go to schema feature, create a new schema
Add a property test, string to this schema, save
Go back to document type you created
Go on the edit layout tab
Try to drop a field from the previously created schema

=> Bug : schema is not found in the list.
User has to log out for making it appear (a simple refresh doesn't work)
