CiviCRM 5.13.1 is not showing “Added By” coumn value
I upgraded site Drupal 7.66 + CiviCRM with latest version 5.13.1 and found out that if you go to any user profile and click on Activities tab then you can see there is "n/a" in "Added by" Column.
But when I click on "View" activity link then I can able to see "Added by" value.
It was working with last version 5.10.4, I think this is bug in CiviCRM latest version. Any help is really appreciate.
