Shopping cart title appears in Simplified Chinese even though the form language is set to English

Hi everyone,

I’m having a language issue with the shopping cart in the Products / Product Basket field.

I did some multilanguage setting in the system message, somehow it stuck with wrong language?

My form’s default language is set to English, but the title at the top of the shopping cart displays Chinese instead of English

The cart displays correctly in English in my regular desktop browser, but it shows Chinese text—including the Simplified Chinese title “产品”—in an incognito window and on my phone. But it should appear as “products”

The form’s default language is set to English. Why does the cart language differ between browsers/devices, and how can I force it to follow the form’s language setting for all visitors?

Any clue?
