Zone 1 Funning Power no matter what.

Please help no matter what my HR zone is, no matter if it’s a tempo run threshold run… my Running power stays in Zone 1? How do I fix it? I tried resetting it and I get the same problem… how do I know what values I should manually put for running power? What tests could I do to get these zones? Any help is appreciated. I’m tired of seeing my running power always zone 1… 

(Please explain any solutions the simplest of terms)

thank you!
