Charge 4 swim tracking misses lengths

[Fraser73]

I've recently been given a charge 4 as a present, in order to help track swims. I often lose count and like to know how much I've done, etc.

I've been getting out of the pool having done approx 40 lengths, often more and the fitbit app says that I've done about 30ish lengths. I clearly haven't forgotten to count a quarter of my swim and often the resultant length count is an odd number, which is clearly not possible when I get out of the same end that I got in at...

Are there any suggestions or tips as to making the swim tracking work better?
