Conditions can be moved using the up/down arrows next to the Condition or at the bottom of the dialog box, or by using copy/paste. When a Condition is moved, the Condition and any actions inside of that Condition also move. If a Condition has an else statement under it, the else statement is also moved. This is because the Condition, any actions inside that Condition, and any attached else clauses are considered a conditional block, and the entire block is moved.
Example:
Condition A
Action 1
Action 2
Condition B
Action 3
Click the Condition A down arrow ONCE, and Condition A and its child Actions are moved as a block:
Condition B
Action 3
Condition A
Action 1
Action 2
This same behavior does not apply when the Condition being moved is part of a compound Condition. To move one of the Conditions inside of a compound Condition down (or up), and, therefore, outside of that conditional block, you need to click on one of the Condition’s up/down arrows:
Condition C1 and C2
Action 1
Action 2
Condition C3
Action 3
Now click on the down arrow to the right of C1:
Condition C2
Action 1
Action 2
Condition C1
Condition C3
Action 3
To move a compound Condition, you need to select the ENTIRE Condition by clicking the icon at the far left of the Condition:
Condition C1 and C2
Action 1
Action 2
Condition C3
Action 3
Click the icon then either drag the cursor down or click the blue down arrow 
at the bottom of the dialog box (not the down arrow to the right of the Condition). A page icon appears if you drag it to an applicable location.
Condition C3
Action 3
Condition C1 and C2
Action 1
Action 2
