Issue Can't change Subscriber to another Customer

[Jacob Grahn]

So I go to change a Subscription over to another user.
I go to the Subscriptions page. Then I click on the Subscription and click Change Subscriber. I click on the customer's name and hit Next, and it gives me this error (see attached picture).
