Does your report show the data on screen before you export it? If not, you will have to add the fields by changing the data.
Another easy mistake is if the fields you are asking on registration are not the actual fields. I would hover over your registration fields and see what they are called or look at the question titles. Another easy mistake is if you aren't sharing questions you may need to grab multiple questions to cover the fields across all paths.
