8.66 APAC - Crazy cadence while walking

Hi,

I took my I2S for a walk after having done a watch reset yesterday. When looking at the cadence graph, we can see that the values are completely wrong... 

I saw similar threads in the other forum's device sections following the new update, although I need to mention that my watch is still on ver. 8.66 (APAC). The pace seems to be fine on the other end.
