My trading Template review for Digital Downloads

I don't know why but recently some of my files disappear randomly from the digital download app or are tagged as "Unattached digital files" so I need to check all my product to see if the files are still here and upload it back (even with no file the app say it was a file so you cannot filter the one without a file). A bit annoying (I have more than 200 products to verify and reupload).
