A few of my Personal Records have updated to times slower than my previous PRs. This happened just recently for my 5K and 1 mile records. I broke both on one run, then two days later on a slower run it said I broke both again, yet the times it showed as my new PRs from that run were both significantly slower than the times from the run two days prior. Anyone else having this issue or know what to do about it? It's incredibly frustrating. I have not changed anything with my watch, the app, nothing. I can see no reason why this is happening.
