on xfinity stream how to change caption language

While watching shows on Xfinity stream (https://www.xfinity.com/stream/foryou), I turn on captions (CC) and the text is in French or Spanish (actually it's French, but I haven't looked at very many shows, so it might be Spanish sometimes).

This is a recent issue, it just started now watching "The Fix" (ABC Series). Up until now, captions on shows on Xfinity stream have always been in English.

How do I change the language for captions back to English?
