Fusion 360 should know he's taken .45 off the stock (the top of which he's set as zero) and compensate for him but unfortunately Fusion 360 has the same problem as me, it's Crystal Ball is in for repair! :D
One of the reasons I wondered what was in the LH side of the screen is that F360 works in terms of setups, each of which can contain multiple operations. I believe (but have not checked) that some operations can be instructed to use the "as machined" rather than "raw stock" as the starting point, but only for multiple operations within the same setup group. I further believe (but have not checked) that typically this applies to 3D operations which tend to be rather more complex but not 2D but I'm happy to be told I'm wrong. So here we have someone either using 2D operations or using 3D operations without specifying that this operation should use the "as machined" state as starting point. Combined with the fact that the OP actually and very specifically told F360 to use the stock as starting height (by missing this one parameter in the operation definition) I'm erring on the side of user error rather than stupid software.

Actually, I'm sympathetic to the OP because it took me quite a while to figure out what a lot of the CAM settings were for (and I still don't understand all of them, but usually enough to make it do what I want) and missing the significance of this one is understandable. Mild "tut, tut" rather than making him stand in the corner with his back to the class
