Google Drive causes 6 entries as attached file

Google drive add-on is actually free and it doesn’t add multiple entry

I made a video to show what is happening, so you can see for yourself:

And it happens when I am using Firefox, Chrome or Safari.

I was using the free version before and haven’t had this issue then.

We tested it in your site as well as in our installation, everything was working fine, however I recorded this from our demo installation: https://www.youtube.com/watch?v=XMyEL9sp7WU

So what is causing this error on my WordPress? I can reproduce it, so I guess it is reproducible for other users as well.
