Let's update your QuickBooks interface to the English language, Thamires.
May I ask where did you confirm the message that say's you're using the English language? This will help me verify which area causes this issue and provide a more precise solution.
We can reselect the English language in your QuickBooks settings to ensure the setting is fully applied. Here's how:
- Click the Gear icon in the upper-right corner of the Dashboard page.
- Navigate to Account and settings, then select the Advanced tab.
- Select Edit next to the Language setting and change it to English.
- Press Save, then click Done to confirm the changes.

You should also check your web browser settings to see if it is automatically translating the page, as this interferes with other languages. Here's how:
- Click the ellipsis (three dots) in the top right corner.
- Go to Settings.
- On the left menu, select Languages.
- Under the Languages section.

Please make sure that English language is at the top of the list of preferred languages and look for an option like Offer to translate pages that are not in a language I read and turn it off.
If the problem continues after trying these steps, please log out of your QuickBooks account and then log back in. Logging out ensures that your account reloads all settings from the server, which can help clear any temporary issues.
