JudithSluiterPost - there is no data between 1hr15min54sec and 2hr35min06sec in your .fit file. Without the data being there to manipulate, there isn't a lot that I can do.

JudithSluiterPost - before you go and drop $$ on a new device, have you tried a factory reset? Have a read of this article BEFORE you do a factory reset though.
