Curve option in Route>Slide disappeared in 16.6

Hi,

I am new to 16.6 version.

In 16.5 or older versions there were an option in Route>Slide that we can change a 45 degree routed net to curved routed net on clicking.

But when I used slide option in 16.6, there is no curve option. there is an option here named "Vertex Action". In the Vertex Action drop down window there is an option of "arc corner" but it is not working.

Regards
