When within the "Inbound Streams" or "Outbound Streams" page, clicking on "Manage Channels" > "Add Multiple Channels", placing the cursor after the "1" and pressing the backspace has no effect which was confusing at first as that restriction prevented entering any number between 2-9 and 20+. Realizing that the number "1" had to be selected to remove it was not immediately intuitive. Request allowing user to delete the "1" using <DEL> or <BACKSPACE>.
