missing track effects in multitrack session

I created a multi track session with a few effects in the effects added to the "track effects" panel. The effects were rendered to the exported session, but not "applied" to the original waveform. After listening to the exported file, I wanted to adjust a reverb setting, but when I open the multitrack session I no longer see any multitrack effects listed in the track effects panel. The effects are clearly audible in the multitrack session window, and definitely not applied to the original waveform, but I can't find the effects so I can adjust them. I presume this is a user error on my part, so I'm hoping someone can advise me on how to re-enable the track effects display so I can edit them.

thanks!
