Forerunner 245: wrong PR extracted from running activity

Today I did my first half marathon and registered it using my Forerunner 245, but somehow it's incorrectly extracting the PR from the activity. This is the activity:

Connect translated this into the following Half marathon PR:

This clearly can't be correct: The total distance is 21.43km and the total time (2:13:02) is copied into the PR, which is obviously longer than the time it took me to run the 21:09km.....

Can this be fixed somehow?

    You can manually set the PB to the chip time

    Thank you for your answer. I have been looking for this option, but can't find it. Does this mean editting the PB? Or the activity?

    In pricinple I would prefer a way to repair the activity, leaving the extraction to Garmin. I have been considering backing-up the activity and then trying to trim it a bit to make it end closer to the finish line. If this screws it up, would deleting it and importing the exported file to restore the original, work?

    This is one of the many "well hidden" features. It can be changed only from the connect website: https://connect.garmin.com/modern/personal-records

    Even after you land on the page it's well hidden... 

    You click on the record number and then you can edit it:

    Thanks! Worked :-). At least I now have the official time in.

    I would still be curious on what went wrong with Garmin and whether this can be fixed, as typically the distance one runs between start and finish is a bit larger than the nominal distance due to not following the optimal patth. The fastest 21.09km in the activity is likely faster that the chip-time.

    What I did was create a workout consisting of 3 phases: I started it at the gun-sound, then lapped when I reached the starting line (~0:17 secs into the activity) and lapped again on the finish. Then I finished the work-out after walking another ~70 meters to be really sure the activity contained sufficient length to allow extraction of the fastest 21.09 km. That's why the activity distance is  slightly longer than a HM. This was the result:

    The initial 17 secs can be recognized. Also the walking after the finish line is visible. Garmin somehow combines all into the PR, rather than picking the fastest 21.09km. My fastest 21.09km would actually be more than 1 minute faster than the chip time, as I ran 21.34km between start and finish line.
