Problem with Event Module Report

We use the event module in Adobe Connect and have recently found that the report doesn't list the attendance status correctly. The report used to show everyone who logged in on the day of the event as having "attended." When we looked at a report for a session we held last week, the report only showed the people who attended during the scheduled time as having attended. About two-thirds of our audience joined before the scheduled start time of 12:00 and weren't counted by the report, even though their polling question responses were listed correctly. This seems like a bug that was introduced by the last update. Has anyone else noticed this? Is there a fix scheduled?
