Health app suddenly doubling steps

Hello. I've had this problem occur twice now where I open the health app to check my step count and see that my step counts for the past ~one to two weeks have suddenly been artificially inflated. when I go to the 'All Recorded Data' section I can see that, for some days, every piece of step data has been duplicated—identical timestamps, step counts, everything. However, it's not always that simple. There are some days where it's clear that it's been double counting, but the counts and timestamps are just a little bit off. I have no idea why this would be happening. I've checked the data sources section and there's nothing in there besides my phone. This really bums me out, because the data getting ruined like this is basically as bad as losing it all. Thank you for any help on how to fix this or prevent it from happening in the future.
