ENDER 4.2.7 firmware, bed traming not working properly, caused by the probe offset

bed traming, ‘front right’ and ‘back right’ is not working. no response unlikely others center, front left and back left.
it seems happened due to the probe offset of X-axis. if I put this value more than -20, bed tramming is working without any issue, however, cannot leveling front left / back left because no offset provided for the BLTouch.
can you correct this issue, please?

thank you.

Correct - there is currently no way to adjust this as per the X / Y offset for the probe.

I recommend you store your probe offset, set them to zero, use those functions, then restore your probe offset.

Anything else will give you incorrect results.
