Prevent sending "locale" query string to the redirect URL?

[Theraloss]

Hello,
we're currently integrating our FusionAuth app with an external provider. The issue we're facing is that when our app redirects to the provider it attaches also a locale=en_US query string that, unfortunately, does break the provider since they only accept en as valid locale.
Is there anything we can do to avoid attaching that value?

Right now I've tried to force a "en" locale with an hidden field in the login form, but does not seem to work with Social sign in.

locale=en_US

When you query the user, does anything show up in the preferred languages? Also, are you using the FusionAuth hosted login pages?

Have you used a network monitor to see if the the local is put into the query string by FusionAuth or the IdP?
