I continued to step 29 and only had 3 items show up in the "all marketing data" step instead of 13 items. I tried to repeat the process and had the same result. Everything up until step 19 was correct.
Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, uninstall Max's Pitch Package, etc. That can make it worse. There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. But if you can't find it there, post your problem here.
Make sure you post in the right category below & be sure to include a screencap showing the issue!
