I downloaded both and loaded them into separate tracks in SONAR. I heard the issue in the SONAR file, there are some little ticks.
However, I then exported the FL Pad file from SONAR and imported it back into SONAR, replacing the SONAR file of yours I downloaded. I put each on its own track, and flipped the phase on one of them. Setting identical levels nulled them completely, so the FL file that was exported from SONAR and then imported back into SONAR is
exactly the same as the FL pad file I downloaded.
So, there's nothing inherently wrong with SONAR's import/export process. The problem lies in a setting somewhere or in something else entirely.
