I finished the whole lab already, but I just realized I forgot to take a screencap of step 51. Now when i go back to the page it needs, it only shows this one pitch, but i need the other 2 pitches.

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!
Ok, well they are still there but there are in the Recycle Bin so you could just go there and Undelete them and then go back to that List View and take the screencap. Hang on, let me get you the instructions on how to do that. They have just changed as of a couple of weeks ago.
Ok, so go to the App Launcher and scroll to the bottom, below where it says "All Items" and just lists links as text. Those will be in alphabetical order and just find "Recycle Bin" and click it.
Then you'll see a list of records you deleted in the last 15 days. For each one you want to undelete, just pull down the menu with the down-arrow on the far right of that row and select "Restore". Then it will disappear from that list and you'll find it back in the active records so you can view it and take your screencap.
