Hearing Spanish in background during Thursday Night Football

We are watching the opening night of the NFL and can hear the Spanish translation softly in the background. I made sure we had English selected as our language and we did. Just for kicks, I switched it to Spanish and it began broadcasting only English—but every other channel is Spanish. I have also had a few channels randomly begin broadcasting with the video description for the visually impaired playing. Assuming this is some kind of Cox bug? Only had Cox for a few months in a brand new house and it is terrible. We have had all kinds of problems.
