Premiere Pro 2018 x Pluraleyes disfuction! Pls Help

Pluraleyes used to work like a charm. Now when I drop content into my timeline to sync it still syncs but at a sinister cost. When the sync is complete PP goes out of wack. I can no longer add layers to the timeline. I can no longer add images to any timeline. The eye balls to the left do nothing to the timeline when toggle (always see top layer even when all layers are supposed to be invisible. The undo button no longer works. its virtually impossible to edit. Anyone have an answer for me?
