Upgrading Architect 2.0 project to 2.1 removes preventHeader
When our projects were upgraded to Architect 2.1, the preventHeader attribute was erased from the ext components across all of our files. Every location that had a preventHeader requires you to go to the component, search for header, enable header, then disable header to get the same functionality.
This means that a manual process has to happen where exports pre 2.1 upgrade are gone through to look for every instance of preventHeader, then setting "header" to false in that component by hand.
Now when converting an old project, I get this:<br>

I don't see a place in the old version of the project that used preventHeader in this case, so I can't verify that it was using preventHeader and got converted or if this is just a general error regarding that new behavior. <br>
Steps to reproduce:<br>
1) Attempt to open older file<br>
2) Accept dialog option to convert file<br>
3) File closes, says will re-open<br>
4) Observed bug, reported here.
