Hart rate zones not correct

Hi there,

Ive set my hartrate zones based on LDHS. When i check these settings they are correct aswell in app as on my watch.

Zone 3 should start around 143bpm.

But every time i run with a hartrate 130 or so my app says i ran all in zone 3.. this should be zone 2.. 

Someting i can do to change this?

Thanks
