From Audacity to Sonar x1. Problem!

Hi!
Please help me anyone. I use Audacity for recording, correcting of latency and cleaning of audio. Now i have done a greit song in Audacity and want to export it to X1 to do effects there. In Audacity i choose an opption :export tracks, so it exports all the tracks which i feated togheter in wave format. But, when i`am trying to put those tracks in x1 they do not much togheter!!! They do not start playing togheter but with time difference. It looks like all my muching done in Audacity is completely gone!
Does anyone know how to do a correct exporting from Audacity to x1?
 
Thank you!
