You're looking at example calls and ad spend. They show how the tracker works. Remove them before you log your own.
Each percentage with the counts behind it.
Spend and leads come from Ads Manager, and booked calls from the number you enter. Shows, closes and revenue come from calls whose lead source is Paid Ads or that have an ad campaign set.
Up to the last 12 months. The date filter does not apply here.
Calls marked Not closed, grouped by the reason you recorded.
