Is my Zuiki controller faulty?

I recently bought a Zuiki controller and have been playing some of the Tetsudou Nippn games native to the controller on the Switch.

When I am playing a game and click the home button on the Zuiki controller, I cannot control the up or down arrow buttons if the controller is in a certain position. For example, if the controller is pushed upwards into the Break position, it will continuously click "up". If I put the controller into the Power position (downwards), then on the home menu it will constantly click "down".

Again, this only happens when I go on the Switch menu. It does not happen in-game. But this is still annoying when I want to quickly put my switch to sleep. So I'd just like to know if this happens for anyone else. Thank you!
