Got New Cable Modem, Want to Remove Old Device From Profile

Subject really says it all. Now I have two devices listed and when I go to the Status page, it tries to use the old modem that isn't attached anymore. It will be listed as an option in Help menus, but the answer is the phone app. I have the phone app and there is no way to remove the old device. To be clear, internet access is working, it's just the XFinity Status page doesn't work properly because it is trying to gather data from my old cable modem but can't find it. It doesn't appear to try the new device.
