Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

When you use the G61 Return to Saved Position feature, and specify any axis to restore, and do not put a offset value, it does not return to the saved location, it does not change that axis at all. It stems from Line 89:

Which defaults to the current position, and not to stored_position[slot][i] as it should.

The online line documentation here: https://marlinfw.org/docs/gcode/G061.html
does not even mention that offsets are an option, so anyone using this command with axis restores is bound to fail.(As I did)

Bug Timeline

In the original code of G61 (#16557)

Expected behavior

I expect it to move back to the proper position.

Actual behavior

It does not move

Steps to Reproduce

for Example if you run:

G28
G0 X10 Y10 Z10
G60
G0 X100 Y100 Z20
G61 X Y  

No movement is seen on the G61. if instead you change that to G61 X0 Y0 it will properly move back to the X10 Y10 position.
a bare G61 does work properly.
