Notifications in English after upgrade

-- url of the page with the problem -- : www.portal-gestao.com
-- HikaShop version -- : 3.2.2
-- Joomla version -- : 3.8.4

Hello,
After updating to the latest version of HS, the notiification emails are being sent in English.
They were previously in Portuguese. How can I get them back in Portuguese?

Hi,

I'm not able to reproduce the problem on your website:

I did get the notification emails from your website in Portuguese.

Hello,

They are in PT again now, I have no idea why.
Thanks anyway!
