In case you are using info-window layout 1 which has a bigger image, the infobox will cut off due to a large content box, you can use the offset values to avoid such problem.
Shortcode for the y-offset
[ASL_STORELOCATOR info_y_offset="60" smooth_pan="0"]
Shortcode for the x-offset
Offset value for x isn't needed for the infobox layout 1, but still it can be used with the shortcode below.
[ASL_STORELOCATOR info_x_offset="60"]
