ghost model in planner/simulation

[[To...]]

I have a program that had a model loaded into it but the model is for a different operation.  There is no model for the current operation.  I deleted the model in the hierarchy. I also deleted everything in the measurement plan that had the word model in it.  The model appears to be gone until I run in simulation, where pops up as soon as I start the measurement plan.  Where is this model hiding?

[[No...]]

Shot in the dark. Does it still exist in the location it was originally loaded from?
