Encountering ATC problem

I created a short flight from Leesburg, FL to Melbourne, FL; flying IFR. Leesburg is about 35 miles NW of Orlando and Melbourne is about 60 miles slightly East of Orlando. I depart from Leesburg, obtain IFR clearance to Melbourne, while in flight I receive an ATC prompt to contact Orlando departure, I'm using the autotune feature, one of the selctions is IFR clearance, it select that and receive clearance from Orlando Departure (ATC) for Melbourne, I acknownledge that clearance and then encounter a problem. Right after receiving the IFR clearance for Melbourne (follwing my acknowledgement) I receive a command from Orlando ATC to land with headings provided, at a runway for the Orlando airport??? I receive no options other than being instructed to land in Orlando. What's going on?? All I want to do to fly to Melbourne, but I don't receive prompts for that destination from Orando ATC? I contunue to receive instructions to land at Orlando, with no option to continue to Melbourne.Ultimately if I ignore Orlando ATC, my IFR flight is cancelled and I'm informed that the flight is VFR. Is there a solution for my problem?
