Event reports have the word 'View' to the right of the contact name - it's a link to the participant record. It's not a selectable column in the report and the problem is that when the report is converted to a pdf the word 'View' gets merged into the contact name which can make this unreadable. Is there any way of removing this 'View' column from event reports? Or making the pdf format better?
This is a bug. In replicating it I saw it was easy to fix, so I did.
