How to clear all images tracked

How do I clear all images or data for an AR session? When I leave my Image Tracking scene then come back, previous tracked images are remembered and never show up in ARTrackedImagesChangedEventArgs.added. Is there a way to clear the data?

I’ve tried the below but the issue remains…
ARTrackedImageManager.subsystem.Destroy();
ARSession.Reset():
LoaderUtility.Deinitialize();
LoaderUtility.Initialize();

Thanks!

It looks like one of those methods should have worked, based on what you have said.
