Dynamic Component Attributes Decimal Rounding

I’m trying to create a dynamic door component where the vertical stiles are 4,5, or 6 11/16" wide based on the user selected option. In decimal format 11/16" is .6875" When I reference the parent in the nested component is rounds the number to 3 decimal places. Why is this happening and is there a fix?

What precision have you set in Window/Model info/Units?

Not at computer so can’t check if it affects DC.

I have model units set to the highest decimal precision

you will find that the display maybe 3 decimal points, whereas its value is 6 points. can confirm by using
check = round(lenx,6)
