Strange results, please check file

Hi, I am Mark, and I recently bought a powerpod to be able to follow up on my progress during the year. I only ride for fun, but I am still interested in the numbers.
Last week I did a O&B calibration run, and after a few tries I think it worked (counting up to 50, turn and up to 100).
But when I did my training ride, I got some weird results.
I ride a fully MTB, 29 inch, tire circumference 2250mm with locked front shock.
I paired the PP to a Polar V650.
I use a new B'Twin speed sensor and a new B'Twin cadence sensor, both without magnet, both paired to the PP.
During the ride I saw the powernumbers rise and fall all the time.
It was a mostly (95%) flat ride on asphalt, where I return after about 15km and follow the same route back home. Only the last 2 km don't match the out ride. There are only a few places where I need to slow down or stop. I trie to keep a steady cadence of about 85-95 rpm.
When I uploaded the file to Isaac, I saw the power going up and down, the cadence changing, and the slope bouncing al over.
Today I paired the cadence sensor to the Polar V650 and did a MTB ride. I seemed to me that the cadence sensor worked fine, and gave me a steady signal. Cadence didn't go down on the smooth streets.
Could you please check to see what might be going wrong ?
Thanks
