You gotta show us the output of the CO list for the person record first to be able to troubleshoot(as Sandy says). That's the first step you gotta follow when the output isn't something that you hoped it'd have been. Additionally, do you have duplicate records in your database? It's worth mentioning that Preview By Person de-duplicate records by email address. This can lead to you seeing data for a different person record in the person profile page, and expecting a particular output, whereas the Email Preview running the script on a different person record altogether (this is one of the reasons why Preview By List is preferred instead). Re- your Part 2 question, you'd have to fomat the calender object to be able to display the output in the desired format. There are plenty of threads on the community already where we've discussed that.
