My personal record for distance ("Farthest" on Modern, "Longest Run" on Classic) is screwed too (Forerunner 220 here). It says 4:02:26 (a duration) on Modern homepage, while it says 14.5 km (a distance) on Classic homepage. The activity was actually 14.55 km in 1h21'00, and I can see it fine when I click on both versions. It's obviously an issue related to the Modern homepage, then.
