Only Xfinity commercials broadcast in Spanish instead of English

My question included the fact that the TV as NOT set to Spanish & had never been set to Spanish.  I did read other questions about this same issue from a couple of years ago & checked my TV before I asked the question.  Again, it was only Xfinity commercials for battery back up that were coming in in Spanish.  Everything else, including Xfinity mobile commercials & business commercials, were in English.  If the TV had been set to Spanish wouldn't all of the commercials been in Spanish?  Appreciate your effort, but that answer does not address the issues.  However, at this point it doesn't matter because at 7:32 last night, all by itself after several days, that commercials switched back to English.  I won't need any help again until whatever caused it comes back.

Unfortunately, that is not something that Comcast has control over. Commercials are run by each individual network and are determined by their contracts with the various businesses looking to advertise on their network. We transmit the broadcast that each network is providing but don't have control of the contracts that run advertisements on the network. 

I have experienced the same exact problem. Same commercial in Spanish. It’s a Comcast/Xfinity commercial, so Comcast has FULL control over this commercial. I have experienced it for several days as well if not longer. 

There is nothing wrong with your TV. Comcast made two commercials about their backup power. One commercial has two English speaking Asian children and the other commercial has two Spanish speaking children. Very simply the Spanish speaking children commercial is catering to the vast number of Spanish speaking people in this country. EVERYONE who watches whatever channel the commercial is broadcast on sees and hears the Spanish. Comcast pays money to these channels to run their commercials a certain number of times per day just like any other business who advertises on television. It is really as simple as all that. And, if you don't want to hear the Spanish then press your Mute button.
