Adjust the angle of the character you dropped into the panel.
A camera angle dialog will open when you press the "Camera Angle" button in the layer properties in the upper right of the editing window.

You can check the angle that you selected in the editing window by pressing "Preview" after selecting the angle. If you check "Auto Preview", you can see the changes in the editing window each time you select different angles.

The editing window will have the angle applied after you decide on an angle and click "OK".
