Not able to review Dataflash log

I can not review my dataflash logs. When I try to review the log files created automatically from dataflash bin files , it says FMT massages are missing, so it can not process further.
APM/Plane Ver 3.4.0

Start by reproducing review of a Dataflash log generated from an automatically created bin file, using the reported APM/Plane 3.4.0 context, and trace where the missing FMT messages stop processing. Done means the log can be reviewed without the FMT-messages error; the issue does not name a source file or test to run.
