Finding Jazzercise in the database

I've started doing Jazzercise and want to add it to my exercises. I can't find it doing a search of the exercise database, although when I googled 'how many calories burned doing Jazzercise', I got a link to an MFP calculator that gives me my total calories burned, but there was no option to add this to my exercises. I thought I'd try to create a new exercise since I couldn't find it in the database, but then got the error message that this exercise already exists in the database. What am I doing wrong that is preventing me from finding this exercise?
