I have one does this too, it behaves normally otherwise and doesn't do it every time you charge.
I think you can safely ignore it and hope next time battery firmware updates it will stop.
In theory re-applying battery firmware might solve it.
However it's complicated as you'd need to put the Mavic on an older version and update again - not without risk and not worth it since battery behaves normally in use.

That has happened to me once or twice, I turn the battery off and on and it normally resets it.

How do you update firmware on one the batteries?

I have one that doesn’t seem to want to charge.

This happened to me when I bought a new spare battery. I think it’s caused by the battery firmware mismatching the firmware of the drone. You may have done a firmware update with a different battery in the drone. I solved it by connecting the drone (with the suspect battery) via the USB cable to my laptop and ran DJI assistant. When I activated firmware check it detected a hardware mismatch and ran an update which also rebooted the Mavic. After that when I charged the new battery fully all the lights went out on the battery as expected.
