Trouble downloading Documents — No file extension

Hi. I'm using 1password 7.1 on windows. Bug for you.... When I create an entry for a new document and drag the file into the entry, it attaches the file but removes the filename suffix from the attachment that is stored in 1password. So, I can upload "test.pdf" into 1password, the entry in 1password is called test.pdf, but when I go to download the file from the 1password entry, the filename is "test" without the ".pdf" in the filename. Windows doesn't recognize the file type and I have to manually rename the file to add ".pdf" to the end of the file name. At that point, the file works fine. Pretty clunky.
