In the machine definition, you need to make sure the pockets/tool mount junctions correctly
In each tool, you need to make sure the mount junction is correct
I would suggest (if the lower turret can NOT use same toolholders as the upper turret) that you define different holding systems for each so you can't load an upper turret tool into the lower turret, or vice-versa.
