CONFIG WARNINGS on 2nd and subsequent departures

[Transair]

I regularly receive flap config and F/Ctl flap/FMS disagreement warnings when pushing back and starting an engine after a turnaround. This never happens on a first flight, but only on subsequent ones.

Does this relate to checklists, state of aircraft or something else? The aircraft is prepped completely each flight.

To stop the warnings, I can lower flaps but this is not a normal procedure during pushback, or clear the messages.  Is this a common occurrence?
