Bug in the custom logo position

By default when i enable the custom logo location, it generates numeric values for the 4 directions.

Which causes the WAH widget not to show ??

It shows when there is NO VALUE in the right/left directions and there is a value on one direction (in my site I put a value only on the TOP direction and NULL values (not ZERO) on the rest of the directions.

It works for me now, but if it is actually a bug it can be helped if by default there are no values at all on 3 directions for example
