User Defined Thematic Definition set not showing fill in cells

I have two versions of OpenUtilities Map running in my office.  One version is 08.11.09.528 on my computer the other is 08.11.09.705 on my assistants computer.  Using the same file and the same UPF, both versions show a different outcome.  The issue I am running into is when I go to create feature classes under symbology for my fire hydrants, the fill disappears in version 08.11.09.705.  I cannot seem to understand why it is doing this.  The hydrant is a cell that is filled.  If I change the Thematic Definition set back to default display the fill comes right back, then swiching back to a user definition it disappears again.  This does not happen in version 08.11.09.528.

Any ideas?  

Thanks
