Cannot modify my favorites list - DirecTV

My Genie remote does not have a yellow button on it and I need to modify my favorites list and remove multiple channels from it. Every set of instructions I've seen to modify the favorites indicates that I should use the yellow button, since I don't have one I have been using the Dash button on the bottom left, however Setup Custom and select Add Channels do not appear as options when I complete the first 3 steps.

To customize your DirecTV channel guide, press Guide on your remote, press the yellow button (I am using the Dash) button to display the Guide options menu, select Change Favorites List, select Setup Custom, select Add Channels ( options do not show up) press Select, and press the left arrow twice. Select Yes, Change Current, and press Guide on your remote again.
