Redline atc after setting tool height crashing into tool setter?

"Onefinity Gen 2 Elite, Redline post processor, tool setter issue.

After Homing machine I have the machine load the tool I’m going to use. The automatic tool changer loads and measures the tool and parks over the setter. The machine stays parked directly over the tool setter up high. When I hit start on my program, instead of moving to the home position or the program’s actual start position, the Z axis immediately plunges straight down into the tool setter causing the redline to have an error. XY never moves first. This has happened more than once and feels like the tool change routine isn’t handing off control to the gcode program correctly. Anyone else seeing this on Redline firmware after the update to one point six point three?"
