Hopper Priotity Bug

Hopper priorities aren't functioning properly. They aren't prioritizing moving items down as they should, instead constantly trio b to send them to the side if it is connected at the side.  If not connected at the side, there aren't any visible problems as far as I can tell, fortunately, but having horizontal storage arrays is no longer possible with this bug. If it is a feature, it is quite impractical, and I believe that many would like to see this removed ASAP. Thank you for your time, and please consider this information.
