Some of Audition CS6 Standard Plug-In Presets are "Greyed Out"

Here we go again... Basically it's just as the title says; One moment the plug-in presets were "clickable" and the next second they weren't - i.e.: Graphic Equalizer (20 Bands and a few others); I had this issue before and I attempted to speak with "Tech Support" but they basically told me to upgrade the program to CC; I instead rolled back my OS, and actually re-installed the entire Master Collection yesterday because of another issue with plug ins, but 3rd party ones that time. I uninstalled and re-installed Audition only this time, and the problem persists. Although for whatever reason, if I open up a new multi-track session, and apply the effects in question, the presets are "clickable", as well as in ONE of the previously saved multi-track sessions, but NOT in any of the other ones that are saved on the computer. Anyone know of any trouble shooting techniques for this issue?
