Ppt 2010 reuse slides formatting doesn't covert properly

[tbrown]

Hello, I'm trying to set up new corporate master slides, and I was asked to do whatever I can to make sure the "reuse slides" feature works properly because we've had major formatting issues in the past. We always want the slides to convert to the destination formatting so we don't click "keep source formatting". The trouble is that the font colors get all wonky, and so does the alignment both on the slide and within a text box (i.e. top, middle, bottom).

Is there something I'm missing, for example a setting under File, Options that would help the formatting change to the new master styles?

I'm using Windows 7 64-bit with PowerPoint 2010. TIA
