WebIf sceen Edision Os Mio 4k question?

Hi, if I'm using the WebIf screen, and I'm in the "BouquetEditor" screen, and I've saved some channels to a Favorites user bouquet, what do I have to do to turn on the "Rename" feature?

Every other option (Delete, Add Marker, Add Spacer) works fine, however the "Rename" button is grayed out.

Thanks!

Nobody knows at all?

Never use that feature before.

I use remote control to rename stuff.
