Imported patches not displaying smart controls

I thought I'd start a fresh concert and import my most used patches. I dragged the patches to the desktop from a previous concert, and dragged them into the new concert, but for most of these imported patches, the smart controls are missing and it just says "Smart Controls" instead of showing the smart controls as they were displayed in the concert that the patches came from. The concert that the patches are from was created in a prior version of MainStage.

Am I doing something wrong?

Mainstage 3.2.3, MacBook Pro (Retina, 15-inch, Late 2013), El Capitan, 2.3 GHz Intel Core i7, 16 GB RAM
