Plug-ins all open in Control View, and I can no longer find the Preference for: 'Open in controls view'

In the past, I was able to go to: Logic > Preferences > Display > Mixer [tab] > Plugin Window [section]... and check or uncheck a box labeled: Open in controls view. This box no longer appears, and my plug-ins always load in controls view. I hate to seem so picky, but I like them to open in all their Editor graphics glory. Any idea where this preference has gone?
