How do I fix HTML lang en Not matching self-hreflang

I see this error on all the pages:

HTML lang en ----- Not matching self-hreflang

I am using the Global canonical URL, and in the general settings of the site, I set the language to β€œen” (which is what I believe is understood as HTML lang).

Is there a way to fix this? Or if this not important?

Any help is highly appreciated :slight_smile:
