Files are downloading as individual folders

Hi, Usually when I download multiple files from a design as a zip file, and I unzip it, all of the png files are within the one main folder. However, all of a sudden, today, when I unzip the folder, each png is within its own folder within the main folder. This adds a ton of tedious steps when I'm uploading the designs to a client portal for approval because I need to keep navigating out of the previous folder, into the main folder, then into the next folder... and repeat for as many files as I need to attach (which is usually 4-10 at a time). Can you please change this back to have all of the pngs housed until the main folder? Thanks!
