Fitness Rewards Bug in iOS26

I've been using my Apple Watch and Apple's workout logging feature for the last 4 years. I've used it to log 99% of my runs, with the exception of testing out Nike's built in run log feature. Today I opened up the fitness app on my phone to review my run when I noticed that my "Fastest 5K" award no longer showed my actual fastest 5k. It says I ran my fastest 5k yesterday (September 21, 2025) at 27:35 despite my actual fastest 5k having been run in August of 2024 (23:52). The fitness app still has all my previous runs logged, so why is my award wrong? It still shows the correct time for my fastest 10k (52:10) which even if you split that in half is faster than the 5k the app is claiming is my fastest.

Has anyone else notice a similar issue since the newest iOS update?
