Unable to Change DirConstraint in SoftEditSrf

I’ve encountered a bug in Rhino where the DirConstraint option in the SoftEditSrf command can’t be changed in certain situations. Here’s how to reproduce it:

  1. Run the SoftEditSrfcommand.
  2. Select a surface (ensure not to pick a specific point).
  3. Try to change the DirConstraint.

This bug has been observed in Rhino 7 as well. I’ve attached a short video to demonstrate the problem.
