izotope ozone plugin settings change

Let's say I'm working on two different songs, A and B. Both use Izotope's Ozone plugin in some of the channels, but each setting is unique to that song.

If I open song A first, then close it, then open song B, B plays fine until I double-click the Ozone plugin to look at the settings - at which point it changes to the settings saved in song A (or whatever song was played just previously).

Is there a fix for this?

Thanks.
