Lost one AirPod Pro — but “find my“ thinks it is together with the other one!

I lost one AirPod pro in my house. However, even though the other AirPod is in its charging case, when I ping them on “find my”, only the one I have makes a sound. See screenshot. When I click on “right” , see screenshot, (not sure it is even clickable) — nothing happens. Unlikely that the battery is dead since this just happened recently. Any suggestions would be appreciated! I could “forget” the earbuds and then reconnect them in Bluetooth and try again, but not sure if that’sa good idea...
