[TYPO3-english] template structure replaced by [INVALID VALUE ("1")]

[David Banning]

After an upgrade to 4.7.1 I my pages do not display.  I notice in 
the root page that the reference to the Page Template Structure
and Subpages - Page Template Stucture that the selection is replaced
by only [INVALID VALUE ("1) ] and [INVALID VALUE ("2") ]

I am using Templavoila.

I have done a update of the reference index under Admin Tools.

Any pointers would be helpful.
