Timecode Issues

Hi,

Im editing a couple weddings for a friends company, he recorded audio from three sources w/timecode (Tenticle lav mics, a feild recorder and from his camera) im having trouble syncing them via timecode. he shot from 2 different cameras. so i pulled all the footage w/ audio into a bin with all the audio that was used. i then select all and create a multi-cam sequence. i click timecode in the options menu and click create single multi cam source. i hit enter and it will sync some of the clips but it wont sync all of them, like im missing half the wedding. it seems like its not even pulling in the lav recordings at all. HELP. im gonna have a meltdown lol
