Flight cancelled

I have boarded the plane on the last day valid of my TWOV (transit without visa) to leave the country, but already inside the plane the flight was canceled and I had to return inside the airport. I got a cancellation certificate with the airline and had the flight re-booked for the next day. The next day I presented the certificate and had my passport stamped again. So now i have two exit stamps on my passport. Is this going to be a problem when trying to enter China again? Thank you.
