ATLS Slave Lost AJS Track

I lost all of the AJS invisible track that connects it to the crossing gate on my ATLS Slave, <kuid2:76656:500012:10> ATLS Slave(TF). I have a lot of crossings, it would be a sad thing to have to replace them all, and I would like to insure this doesn't happen again. Any direction?Thank You.

This could be a layer problem. Ensure you are editing track and placing objects on the route and not on the session.
