Roundtrip AAC not showing clip indicators in OS 10.8.4

I'm trying to use AU Lab to run RoundtripAAC and audition Codecs to check Masters for overs. I have recently updated to the latest version of Mountain Lion (10.8.4).

When I instantiate RoundtripAAC and the plugin in window comes up, it comes up in "General View". When I click the dropdown menu to change to another view, there is no other view to select.

Out of curiosity, I downloaded AU Lab and RoundtripAAC today on a computer running Lion. When I pulled up Roundtrip AAC, the other view was available and everything was working properly.

So now I'm assuming there is a compatibility issue between Roundtrip AAC and Mountain Lion 10.8.4.

Please help me get the clip indicators up so I can check MFiT compatibility on my masters!
