BHV-14852: Fix initial position to match default position.

###Issue
The "Direction" button is shifted when the top position value is omitted when setting the position. This is caused by a mismatch between the initial top position of the "Direction" button, and the default value that is set when the top position value is not specified.

###Fix
The initial and default value for the top position is now the same.
