Acrobat Online not opening .PDF files but will open .pdf files

New Here ,

Our organization has a system that generates files that are .PDF (all uppercase) extension.  Reader will open them fine.  When I try to upload them to Acrobat Pro Online which we are subscribed to, it tells me "File(s) not supported." All I have to do is rename the file to have .pdf  in my Windows File Manager as the extension and it will upload fine.  While this doesn't sound like a big deal, doing it 30 or more times a day is a pain.  Is there something that changed or a setting somewhere in the Acrobat Pro Online that can be flipped to stop this.  It used to upload them fine.
