Owner is sometimes displayed as "false" for random users

We use this module to have participants upload .mp4 videos that are up to 100mb each and have done so with hundreds of different students over the last year and half. Over time I would see an owner called "false" and for the longest time I always thought it was a user. Turns out it never was, we have never had a user named "false", this seems to be an error instead. We also have it set up so the users can only see their own videos, therefore if they upload and it happens to be assigned to "false" instead of their own username, they don't see it. And in addition, if it the video exists online already with the username "false". They are unable to upload the video with the same name anymore since they cannot overwrite it. I know I am using an older version, therefore I wanted to check if this was a known issue. I am not sure if many others use the module the the way we have. There may be a moment in time that there is 10gb worth of videos online and participants uploading videos randomly, and I have always been hesitant to do an update to the most recent version, but if the most recent version fixes this I may do so. Please provide any support possible and the sooner the better since this is now becoming a visible problem to me, thanks.
