Blend Surface - Rhino 8 / Curvature Issue

@pascal, I also tried to build another object with the same apoprach. This time the profile curve was built with ADJUST BLEND CURVE with CURVATURE continuity. The surface was built with SWEEP 2 RAIL with CURVATURE surface continuity. The result is not smooth again, even with adjusting REBUILT CROSS SECTION. Also surface is nor reacting as soon as I am changing Continuity values. It looks like a bug to me. Can you please review attached file and pictures?

EDIT: I restarted rhino, and now SWEEP 2 RAIL works properelly. So this must be a Bug for sure. However, I had this issue several times during this month.

Please let me know what to do. Should I reinstall rhino?
