Not a problem. Just trying to give constructive feedback.
While Steam big picture does use the bumper buttons it's a little unusual.
Think you'll want to stick with the more standard controls.
e.g. A to select.
B should always go back if in a menu (currently doesn't)
Left Joystick and D-Pad to select menu items.
Could leave the bumpers, but I'd probably remove the text indicating to use them. Most users will probably use the joystick/dpad, and those that figure out the bumpers fine. Yes it's an extra click, but it's so simple and ingrained it's not an issue. You could even not require the click, left right to choose the section and then up down immediately starts selecting options to toggle.
Anyway just some quick thoughts.
