Shared Parking Spaces not freeing up after upgrade to V18

[dmat1175]

We are running into an issue since the upgrade to V18 where the shared parking spaces are not always freeing up after the call has been picked up. The shared parking BLFs will remain lit up and the active calls will show the person that picked up the call talking to whichever shared parking space the call was parked on (SP1, 2, etc.). If we pick up the shared parking spot, it will just play the hold music. Hanging up the call will free up the parking space. It is not happening with every parked call but it is happening frequently.

The phones are a mix of Yealink T53Ws and T54Ws running 96.86.0.20 or 96.86.0.23. I was hoping manually updating some of the phones to .23 would fix the issue, but it does not. It has not happened if our secretaries pick up the call from the Shared Parking BLFs on their Yealink EXP50 expansion modules (only a few of them have these attached to their T54Ws).
