Unique Plug-In Lateny Issue only in 11, not 10

[boomstand]

Hello all, this is my first post so try to bear with me, haha.

I know there are a lot of posts about latency issues in 11, but I haven't seen anything on this particular issue.

When I track and play back, everything is where it should be. No latency. As soon as I add a plug in, the latency begins, but this is the weird part. If I turn on Delay Compensation, the track that contains the plug in is on time, but the rest of the tracks fall behind. If I turn off Delay Compensation, the reverse happens. BUT, this problem does not actually appear until I simply arm and disarm another track that does not contain a plug in, which led me to believe that it is a bug. This appears to be happening with any plug in I use, and the amount of latency seems to be appropriate with the amount of delay compensation the plug in requires. The issue is non existent in 10. I am very puzzled by this.

Any thoughts?
