I've reported this to PW and am waiting to hear back. If anyone has solved this please let me know.

I first found this to be a problem a year ago, but, have been off line until recently. Now once again this is an
issue as during shutdown obs script the scope while parked, ACP is never told the park is complete.

May just dump parking entirely and run auto flats to a safe alt az which while effective is a mighty poor work around.
