Main Menu is on a layer, that is then inherited across all layers (above base layers on other layouts). I've had issues with modal layouts.
No worries, I fixed it all, one has to remember that invisible objects remain interactable! I thought I'd share this. If this does belong to help section, then I apologize. I wasn't sure at the time at posting.
Think I'll go with destroying and creating; at least it'll keep the amount of objects minimal.
