First layer cal. and Z Live offset not saving properly and/or not being applied when printing

I have an issue where after I successfully run Calibrate XYZ and First Layer Calibration while the Z live offset value is saved, when I subsequently attempt to print anything, that value is not applied.  This means that if my Z live Offset is -0.5mm, each time I print I have to increase the value by another -0.5mm, but while that new numerical value gets saved it is never actually applied to the Z axis applied.

For Example

First Layer Calibration run and adjustments made Z Live = -0.5mm

Start first print and nozzle is too high... adjust Z Live so now Z Live = -1.0mm.  Print finishes.

Start second print and nozzle is still too high... adjust Z Live so now Z Live = -1.5mm.  Print finishes.

Start third print and nozzle is too high... adjust Z Live so now Z Live = -2.0mm.  Print finishes.

Start forth print and nozzle is too high... adjust Z Live so now Z Live = -2.5mm.  Print finishes.

etc...

My SPINDA is secure (not moving during the print) and I've tried adjusting it up and down and re-calibrating.  That only changes the amount I need to adjust Z Live and still never is applied correctly when printing.

I've re-run though the calibration steps in the manual many times now, and it still hasn't been resolved.

Has anyone run into the issue before or know how to fix it?
