Effect of Plugin Can be Heard But Not All Plugin's Are Listed in Logic Pro X

I can't seem to get around this problem and I haven't seen an answer for it anywhere. I'll use my Kick Drum as an example. I know there's plugin's on it. I hear the effect they have on the Kick Drum but. they are not listed..? They have simply disappeared?

What's even more weird is that SOME other plugin's, on other tracks, DO show up? I have an Soothe2 EQ plugin and a SSL plugin that show up fine.

Again, I hear the effect but the plugin is not listed...?
