Notification sound settings don't follow what's specified in the app

Hi Neighbors,I just set up an additional video doorbell on my account. On the individual device settings I have specified what I want the notification sound to be. However, it doesn't seem to work that way. When I get a notification on my iPhone, it sounds like windchimes in addition to the specified sound.Is this an iPhone issue and not a Ring app issue? I've looked, but can't find anything in the iPhone settings specific to the Ring app. I'm a noob on the iPhone, having started using it as opposed to my previous Android device. Thanks for any help!
