@Dracolich2011 There's no way for you to remove and add back an expansion. But you can ask a support rep to do that for you, either through the standard customer support channels:
https://help.ea.com/en/contact-us/
or through EA Help on Facebook or Twitter.
Either way, please ask that the "entitlement" for Supernatural be removed and added back to your account.
If support doesn't help, please let me know. You might also need to wait until Monday to get a reply from someone who understand the problem; I would guess the support centers are short-staffed this weekend.
