Garmin Connect (and Mobile Apps) displays future dates in the sensors section where battery levels are reported.

The problem occurred when I had the Edge 1000, one training session was saved on such a date. Now I don't have it anymore and I have the same sensors paired with my Forerunner 955, but the wrong dates are still there, so I can't see the actual battery levels. New battery readings are ignored because they are older than those from 2038. I have one new sensor, everything is fine with it.
How to fix it? I am writing with Polish support, but they are not very familiar, they suggest, for example, checking the clock setting of my laptop...
