A bit confusing that I am able to select a pre-defined (or created) strategy, but the section name is filters.

I understand why (at the end of day these are filters, and you can modify them at your will).

Option 1: there could be a dropdown item for "filters" only, not to select a strategy

Option 2: renaming to strategy

I don't feel any of them is better then the existing one, sorry :S
