Apple Watch steps get overridden by the phone steps

My Apple Watch steps are not being counted in the pacer app. Pacer is taking steps from my iPhone. I have set iwatch as priority in data sources.

if I go for a walk only with my watch and come back near my phone , the steps go back to the steps that show on my phone. Pls help and fix it. All this while it was updating the steps and not sure what happened all of a sudden.
