Reports - Campaign log - related name - not working

If i create a report and include the field ‘CampaignLog/RelatedName’ the report is always empty.

This was mentioned here: https://suitecrm.com/suitecrm/forum/bug-tracker/3962-reporting-on-campaign-log-related-name
And here: https://github.com/salesagility/SuiteCRM/issues/1779

It is still a problem with 7.9.10

Maybe you can help make that Github issue more complete. Can you check both your logs

suitecrm.log
php_errors.log

at the moment when the Report fails?
