P4 Pro battery will sometimes not turn off at end of flight.  High use, so I know how to turn off.  Happened twice in 2 weeks same battery.  Requested firmware upgrade was completed and OK after first time, but then happened again.  Battery also "ignored" auto return home and land.  Indicated battery low at 31% and beeped, but no return home at 24% or 18% as it usually does on close in flights. Flew it in close as battery was used and it just hovered there and never went into auto land.  2 other batteries fine.
