Bug? Bug or my mistake?

Sometimes after editing a Layout using the Designer I see a grey windows instead the views (that visible before).

This problem is replicated in the connected device designer and in the UI cloud.
For the affected layout file and problem screenshot please see the attached files.

Not a bug.

pnlAuth visible option is set to False so it is invisible.
