Modifying Account Filter - sheet doesn't match wiki

I recently added the Account Filter sheet and am having some issues modifying it. What I see and what the wiki describes are different. Aside from the visual being different, the only formulas I see are:
A5: =transpose(G8:G12)

I would like to figure out how to modify the columns (I don’t see vlookup in the formula) and how to show more rows. I see 19 rows currently; I would really like to see the month to date.

Thank you for any help you can provide!

Please unhide the columns to the right of column E. This might help with your quest. At the bottom of each sheet is an add button with a box next to it where you enter the number of new rows to add at the bottom. I would reload the sheet again and start fresh.
