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?
