Packaged Apps showing up as ‘classic’ Apps on Leopard

I'm building a 10.5 image on a G5 running 10.5.2. I'm using LogGen/Pkgen/Packagemager and it's worked in the past. I know I'm doing something odd- but I have no idea what it might be. I'm trying to package up Office 2004 specifically. I've rechecked my packaging steps, and I haven't changed anything that I'm aware of (I'm sure I must have missed something). Anyone have something like this happen?
