I've Typo3 4.5.5 and Templavoila 1.5.5 installed and I got this strange problem in the web module when I select it the right content where the module prints the toolbar and the content the page title and the toolbar is always printed two times regardless of any content in the page? When there is content in the page the title and the toolbar is on top and at the bottom and the content is in the middle. How can I fix this problem?!
This is not an answer, but I can't upload images in the comment:
Do you have a special theme/backendlayout installed? The info message in my installation looks different (and ist not repeated, 4.5.5, TV1.5.5):
