Z position unknown after autohoming

I recently updated the firmware on my Gmax Gcreate 1.5+ to Marlin 1.1.8
Now after autohoming the printer the x and y positions read the correct values but the z position will read a set of characters. "*,-(" on the LCD screen. After this happens the printer will not move in the z direction and autohoming the printer again causes head to raise in the z direction indefinitely until it is turned off. The BL Touch probe seems to be functioning properly still.

We have seen this happen in a couple machines, currently the only fix we have is to replace the electronics. I would recommend going back to 1.1.1 until we can find a solution.
