[TYPO3-templavoila] TV Page Module not showing "Main Content Area" and "Create new element" icon

[Joerg Wagner - DigiLog multimedia]

Hi all!

I experience a strange problem in Typo3 4.0beta3 with TV 0.6.0 that I have 
never seen in my T3-3.8 / TV0.4.0 installations:

When I add new pages and try to edit them in the TV page module, the BE does 
not display the "Main Content Area" box and thus no "Create new element" 
icon.
I had a look into the database and found the the field "tx_templavoila_to" 
is !=0 for all affected pages and is =0 for pages that show the "Main 
Content Area".
As far as I can tell, this field has always been =0 in my old installations. 
If I reset it to 0 the missing "Main Content Area" reappears in the BE.

Any hint is welcome as I am completely clueless about what is going on!

BTW:
Where is the right place to post TV bugs? I am quite sure it is NOT in the 
Typo3 bug tracker.
