We have a problem when trying to export data from a Campaign inside “Opt-Out” or any other subpanel as it does not export all entries (all but last entry are exported) to the newely created target list.
The problem was fixed when i set the ‘disable_count_query’ to false inside config_override.php
$sugar_config['disable_count_query'] = false;
But does this property impact performance and / or is there another way to solve the problem above instead of using the “fix” i used ?
