Duplicated copies sent

Today both my co-worker and I ran into the same issue. We both created a document to send out for signatures and after hitting "send" there were duplicate documents sent out. In my case both documents had people sign and I received notifications for both. I then went back into Adobe sign and went to the "Manage" tab and I saw both documents listed. I cancelled one so that I would not have a duplicat. Once cancelled, both copies were somehow deleted. My coworker went through the same process with the same result.
