Hello Steven!

I am working on support of my PDK technology, so I switched scaling to absolute values for convinience of matching with my DRM document.
And I see that strange bahaviour (see attached video)


[steps to reproduce]
1. set tech scale to absolute values (nm in my case)
2. put layout resistor using MOCMOS tech
3. open resistor object properties and press apply

[observed result]
W/L values are multiplying some big number any time apply is pressed
