I have a MetaModel with four component models. I quit QS and restart it. I bring up the MetaModel and it looks fine. But if instead I bring up a saved layout containing that MetaModel, it appears to contain five component models, where the fifth is a ghosted replicant of the first model. Interestingly, when I hit the Run Backtest button, all the real models show loading, but the ghosted one does not. Unfortunately, if I am fooled and think that it's really there and hit Remove to get rid of the ghost, it removes both the ghost and its source model, leaving me with three.
I am tired of my new ghostly friends. Please exorcise this issue.
