What setting am I missing

Auto constraints are off  
Draw a rectangle 100mm x 100m in free space.  
More… Offset box by 20mm  
Draw rectangle on right side touching corner of offset box 20mm x 140mm  
Update width of new rectangle from 20mm to 30mm  
All is good

Repeat on left side touching corner of offset box  
Update width of new rectangle from 20mm to 30mm  
Offset box shifts to the right???

Hey @Wrightwells,  
Lock the offset box or the edge of the box which is required to stay in place and it will work as expected.

Thank you for your time in explaining a work around.  
I played with locking points and discovered that would solve the movement but …

Is this not a defect or a feature.  
The original rectangle is the origin, the offset should always be an offset, and it appears that the software assumes the left most point is the locked point in space even if it is not locked and has no constraints.  
If a rectangle is added to rectangle created from a centre rectangle and not an offset it’s not the same experience.
