That's really confusing... It shouldn't have anything to do with the php file as nothing was changed to pull the header. I don't understand though how one file could be showing something different like that when it's the same template. You could maybe try looking for this in your myvbindex.php file:

eval("\$index_header = \"".gettemplate('index_header')."\";");

And replace it with:

eval("\$index_header .= \"".gettemplate('index_header')."\";");

Hopefully that'll work.
