When I fly the a330 200, I hear a sound right before touchdown that sounds like I am touching down, but I am not, and the aircraft/physics doesn’t move like it touched down. Then, about a second later, the second “real” touchdown sound happens, and the aircraft moves as if it has touched down. This is followed by a third sound when the nose gear is touching down. Is the first sound a glitch? This happens in every landing with this aircraft.

Hello,

Please try "re-streaming" the aircraft; may resolve the issue you're experiencing as things may have not loaded correctly since first initial-load. 

Thank you
