Audio description won't shut off on TBS only

Yesterday out of nowhere audio description started on TBS. As far as I can tell it is only TBS and it is SUPER annoying. I tried every fix. When I click the down arrow and over to SAP, audio description is listed and there is a check box next to it - there is no way to get rid of it. I've tried the voice remote and I have been into settings. It is off everyplace. HELP - we watch TBS all of the time.
