FW 5.51 Wrong Zone Graphs in Garmin Connect

When I check today's 100k ride, I saw that my HR and PW zone graphs were totaly wrong. I always watch my zones in riding and I checked Strava's log too. And I saw strava's graphs were true. What's the problem? Is it about the device or garmin connect app/website bug?

Have you checked the zone settings on your Garmin?

For today's workout, there is no problem. I have not done factory reset or something. Well it worked perfectly. But stability problems such that seems randomly and boring... :/
