I'm not sure what has been changed for this option

Say,  I have a extrude feature with 5 closed profile but I only select 2 in the selected contours for extruding

Before, I could edit the extrude feature, clear all the contours then I can exit the extrude features with all 5 closed profiles extruding by default

Now with SW 2016 sp4, this doesn't seem working - what am I doing wrong here?

Thanks,
