Show all results from select filter

Brad, it has always worked like that:

Dropdown select field - trouble filtering on ALL condition

You need to use the condition in the query builder. [Screenshot 2022-07-15 at 9.50.27] So click this icon and select your $_GET.ev variable there. This means the filter will be applied only when the $_GET.ev returns a value, otherwise it will not be applied.
