Your admin control panel is going to have whatever photopost style you set it to so thats not a bug or issue. You can change styles in admin layout options
When you add a favorite its ajax so the link just changes to say added. when you refresh the page you will see it says remove from favorites
As far as the photo options menu this is something we are working on they once again changed the vb4 css in the final so I need to track things down a little.
