From the screenshots you provided I'd say it's possible the layout template is in the wrong place. Make sure the contact.html you use as a layout is in the right place.
If this is a basic fluid template directly in typo3 make sure the file is in the place you defined in your setup typoscript. Default would be something like this:
layoutRootPath = fileadmin/templates/Layouts/
If this is inside an extension the correct place for the layout template is
Resources\Private\Layouts
Be aware that in more recent extbase versions the naming conventions are more strict and require a capital first letter for the html files (so Contact.html)
