Apple Watch 7 won’t display resting heart rate and walking average after update

I recently updated my watch to iOS 9, and now all of the sudden the Heart app will not display my resting heart rate, nor will it displayed the walking average. All it shows is two dashed lines for each. I have never had this problem with any Apple Watch or any other update. I know the app is working properly because it does display my current heart rate. When I realized the issue yesterday, I noticed that somehow Background App Refresh for heart rate was turned off (assuming it somehow did that during the update) so when I turned it back on, it seems to have worked but now it’s not working again.
