Zone minutes shown twice, but not the same numbers

As in image below. 

First says 1h 16 min fat burn, than 76 mins fat burn below that. That line is fine.

Than it says 0+30 mins Peak + Cardio, but below that it says 60 cardio+peak minutes. 

Given that the entire exercise was 4 h 10 mins suggests it should be 60 mins cardio + peak.

But something is not adding up in any case.

I've checked with ten last exercises, happens every time.

Fitbit does that with a lot of numbers; distance, steps, km's, etc. etc. So it is not an uncommon experience for Fitbit products.
