When I tried to create a new pitch, the fields that are displayed are not showing up the same for me. Is there a way I can add more fields to fill in?

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!
It looks like you are trying to do the first part of 2a after already doing the latter part of 2a where you deleted those fields? Maybe because you forgot to do the screen capture before so you are going back to get it now? If so, it's ok. You should be able to get full credit for it, even with those fields missing now, because you can still fill in a value over 100% for equity percentage and it will still show the error message properly. That should be good enough for you to get full credit, even if it's not identical in every way to the example shown in the instructions.
