you left out important information by not mentioning that you were using a build from source code you obtained from the source code repository and compiled yourself with Visual Studio, and not an official version of any deployment package of mojoPortal.
these fields are only in the source code repository they have not yet made it into any official version of mojoPortal.
anyone working from the source code repository should know that they need to rebuild the entire solution and visit the /Setup/Default.aspx page to run any upgrade scripts. the upgrade scripts would fix your stored procedure(s)

please in the future if you have problems with builds you created and deployed and not with official version deployment packages, you should ask questions about it in the developer forum and not report it as a bug.
