This is most likely, because in freedive mode the dive is recorded with 
a higher sample rate. For a normal dive the sample rate is always 4 
seconds. I quickly checked the Uwatec manual, and for apnea dives it 
says: "the logbook is updated every second". Thus a sample rate of only 
1 second.

The first step to fix this will to figure out where and how the freedive 
mode is stored.
