Rhino 7 - Slide Edge Command not working

In the official Rhino 7 licence, there is a button for Slide Edge - under the SubD menu, but when clicked on it, it gives an error: Unknown command. Is this something that can be fixed?

Hello - please run the ToolbarReset command and then close and reopen Rhino - does that sort it out?


Hi Pascal,
The ToolbarReset sorted all, and new SubD buttons appeared. Thank you so much for your help.
