BUG about Microns Unit accuracy

Hi all,

I tested both APD and Allegro PCB at 17.2 version.

I found some bug about units accuracy for Microns.

at the first time it set the Accuracy value with 3 (see the pic below)

even if I can set the value to 4, action was canceled and back to original value 3 without other change value. (other value didn't changed to 4 accuracy)

and I also set the value to 2 so made it like below

after then, I can not increase the value to 3 again...

when I increase the value to 3, the action was canceled continuously..

Is there any way to set the Accuracy value to edit some Allegro script manually?

regard.
