Appian Interfaces 103 Missing PF Tables

Hello I'm trying to set up the four record types for the Interfaces 103: Build Complex Interfaces by Adapting Patterns course, but it seems the PF_ACCOUNT, PF_ACCOUNT_TYPE, PF_TRANSACTION, and PF_GOAL database tables are missing from my Appian community environment.  Does anyone have a way to manually add the tables or reset my site without losing all my work?  Or is there some requirement I'm not aware of?
