Not able to delete a deactivated device

Hello,I have a new Ring device, but I am not able to delete the already deactivated device from my app. The old devices do not show in the menu when I log in to my desktop account, but my phone app still shows two old deactivated devices. I have read instructions about going to the device settings of the old device to delete it, but the "device settings"-menu isn't even visible when the device is already deactivated.
