Scrapebox Dofollow Checker Freeze

When the Dofollow checker is completed or stopped after checking a large amount of links ( 10,000 plus ) The amount of threads goes down between 1-5 and stays there. Scrapebox won't allow me to download the list as long as these threads are still open.

I've waited 6 hours + so I know it's not a matter of letting the websites finish loading.

I'm sometimes able to turn my wifi off and that closes these threads. However, is this a common issue? Is there a setting I can change to keep this from happening?

Here's a screenshot of what it looks like.
