Ender 3 BLTouch Probe Offsets with Sprite Pro Extruder

My Machine: Ender 3 4.2.7 with Sprite Pro Extruder with an X-axis extender bracket from Printables…
My setup has been working fine for some time. Recently I tried using Post-Processing_Script: Pause at Height/Layer. Of course it did not work with the stock firmware.
I came across this web site and installed your latest Ender 3 4.2.7 Sprite Pro firmware.
My original offsets: M851 X-27.00 Y-60.00 Z-4.40 worked great.
With the new firmware I tried to set the offsets as they were. i.e. M851 Y-60 gives error:
?Y out of range (-50 to 50).
Is there a way to change the max offsets?

i have the same issue, i cannot center the probe on the Y axis due to a 49.9mm limit. seems counter productive to add limitations like this.
