Thanks to alperenakyuz I have had some mild success. I have been able to delete one grid actor and replace it will a different one after selecting an option from the menu. Sadly it still is not passing the instance that is being used. It randomly selects one from with in the world. Here are a few screenshots of the changes that I have made to get to this point.
Grid BP that the mouse object overlaps and opens the menu after a left click.
Menu BP - sequence begins after a specific option is selected
Grid selected
A random grid is selected the be deleted and replace with new grid actor. (It is different each time I test it)
