Rating report in OTBI - displaying multiples lines where course title has been changed

Content (required):

I've set up a really basic report to view course ratings using Learning Records Real Time:

Rated By, Assigned Learning Item Title, Rating, Rated On Date, Rating Comment

I'm finding that if a course title has been changed in the past, the report is displaying a line for each version. Which makes it look like a course has been rated twice as often as it actually has. How do I get it to just display one line of data, using the current version of the course title?

Should I be using a different field for the course title?
