Imaging is missing from Plug-in drop down menu

No, but that was a problem I had in a previous project. But I just did figure out my mistake. When I created a new project to hold the single master track, I somehow got the master track onto an incorrect track. I don't think it was a normal "audio" track, though I didn't think an audio track could load into a software track, but regardless, the track I created for the master track was somehow incorrect. I made a new project and created a clean new audio track and after placing the master into it this issue resolved. Thanks for your help!
