Reinforcing bars changing when closing file

I am placing reinforcing using the Single Rebarset placement tool. Once I have placed thebars in the correct location I save and exit out of the command. When I exit the file and re-open it I notice that the reinforcing bar's cover have changed automatically to the outside of the concrete.

Is this because of the method of placement?

I have attached a video of my procedure and what happens once I re-open the file.
