My region is set to United States (English). Why is Microsoft trying to charge me in...

i have found my own way to change to english subs and language no bug in content

change the region setting to english speaking country like united states or united kingdom download the content again do change the system language to english (united states)

this method helped me get rid of french content in fable 3

do change it back to your region after download

I've just kept the language as English but changed language region to english (United States) kept location to United Kingdom and the keyboard and dictation is English (United States) and that's fixed it

is your region spanish in the settings ?

u may change it to english region like united states or united kingdom.

tell me if that solved it.

but remember if u want to buy somithing in the store change it back to original country or u may have problems

Good Idea, I will try it...

It says English (Canada) on all of the pages except on the Page after I click "Change Payment Options".

This goes to the Xbox live Billing contact information page. This page region is English (United States). When I click on this in the lower left it allows me to select a new region. I click English (Canada) but it goes right back to the Billing Contact information
page for English (United States) so unfortunately it doesn't work.

I already have my billing account information set which works fine on Xbox.com with Xbox One purchases but not when I try to purchase Xbox 360 software. (or download the free gold games)

I think i have the solution for this.

Your language setting and region setting in Windows 10 must match. I've had my region on The Netherlands and language on English (US) and it would not show the text. I installed the Dutch language pack and after that the text would show, in Dutch. I then
change my region to United States and the language to English, and now the text is showing in English.
