Right Earbud Occasionally Charges & Ghost Bluetooth Pairing

The right earbud of my sony WF-1000XM3's sometimes doesn't charge. I've cleaned it consistantly. When I put it into the case and the light on the earbud goes red which I assume means it was detected but the light on the case doesn't turn on. Bearing in mind that the left one works fine and consistantly charges.

Something else that might be connected is, the WF-1000XM3's randomly connect to my phone even if they're in it's case.
