Video without corresponding Tweet

#1

Using the analytics Video Activity dashboard (https://analytics.twitter.com/user/username/videos), I see a broken video thumbnail in one of the videos in the ‘videos published over this period’ listing:

If I click on that, I get a details modal that shows detailed stats for the video, but still with the broken thumbnail, and no associated Tweets listed:

Has anyone seen something like this before? If so, any ideas why it is happening? Maybe there was a deleted Tweet?
