You likely have at least one servo reversed. When that happens the servo center and extreme positions is not the same for both sides leading to the issue you are having.
This is because "center point" (AKA 1500ms) becomes different for each side when one servo is reversed.

You can cure this mechanically by adjusting the servo arms and linkages so you get identical movement, but at center the arms will not be in the same position on both sides..

Or you can cure it in the TX. If you attempt to fix this in the TX you must first establish how far the servos and surfaces can travel in each direction then take the LESSER motion for both. However start by setting servo travel to 150% so you first establish the full range of motion. You may find this gives you more than 20 degree deflection..

If you cannot get more deflection or the servos are binding at extremes you can set both servos via the TX to give you the 16 degrees down.

You may also need to set center points, etc.
