How can I make my custom app list show up properly in MDT 2012

How can I make my custom app list show up properly in MDT 2012

I have an MDT task sequence that installs an OS and presents an
application list based on your OU choice (differing departments need
separate applications). When booting to WinPE and running the task
sequence the selection options show properly and install fine.
However, when running the task sequence as a refresh from Windows, the
application only shows the default panel with the sample application.
According to the logs, it is accessing and running the right file (plus if
it couldn't find the file, it would error out the task sequence) but not
displaying properly.

I could use some pointers on what is going wrong.
