Retrolouge track in a project suddenly disappearing?

Hi all, another issue I’m having is all of the sudden one of the instance of Retrolouge on a project of mine suddenly dissapeared? All the inserts and sends and all that still exists however I can’t bring up the VST itself and there is no sound being generated. Any clue why this happens?

I didn’t save the preset unfortunately and the tune is mostly done. Grrrr…love hate x10.
