By accident, I delete 2 of the Meeting ID 21 and 31. How I can get it back? Otherwise,
all meeting data should have 13 items, but mine is 50. How to fix it? Thank you
Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, eg. uninstall Max's Pitch Package, etc. That can make things worse.
Before you post make sure you check the Help FAQ for an instant solution first. Then, if you can't find it there, you can post your problem here and we'll get to it ASAP (within 24 hours), but be sure you:

Well it looks like you repeated the data import multiple times. You should only have 10 Meeting records, with IDs of Mtg-01 through Mtg-10 so you could delete all the Meeting records above Mtg-10. Why do you think you want to undelete Mtg-21 and Mtg-31? All Meeting records above Mtg-10 should be deleted.
If you really want to undelete, let me know and I can tell you how.
