What do the 'All Active Deals' and 'Filtered Total' mean?
All Active Deals reflects the total value amount for all deals in an active stage (an active stage is any stage that has a probability % that is not either 0% or 100%. This could also be known as won and lost deals, depending on if that has been customized in your account. Archived deals are not included in this total).
Filtered Total reflects the value for all deals that fit with the filter you've applied.
