Version 2 Beta 1 Grid Question

I've just installed Ver 2 Beta 1. I'm using a CSV file as my DB source and the grid is in an iFrame. While I only have one file in my csv DB (41 columns by 1 row) it displays 21 rows with the empty rows containing the word "undefined." Should I go back to the previous non-beta version until a beta 2 comes out. I need to deploy this page soon. Also getting some strange scroll behavior.

Thanks for any answers.
