KHRD has always been in English for me. Even tried with with my TV service provider and also straight from the antenna.
Maybe you have accidentally enabled the secondary audio. Finding where its enabled could be the real trick.
It could be a setting on your actual TV. Check your remote for ""SAP," "MST," or "AUDIO" or even check in the menu for adjusting secondary language audio.
It could be enabled in hardware attached to your TV that provides your service. Things like a Roku, Apple TV, any kind of streaming stick or even your A/V receiver.
Then there could be the software - your provider; such as YouTube TV, Sling, etc. There could be secondary audio enabled there. You will have to look through menus to check.
Good luck, or rather, buena suerte.
