Loss of sort by aisle rendered app useless

I have been using this app for a few months. It had actually made shopping somewhat easier when sorting items by aisle. Now over this past month that function has been rendered completely useless and all items show aisle may vary for every single item on my list. Nothing has been recently rearranged in my local store. I suppose its back to paper and pen list for me. Come on people! Ive just had a major spinal reconstruction surgery. I dont want to play Wheres Waldo. I need to get in and get out.
