Change the size box add card Box - Continue Shopping

I have Joomla 3.8.1 and VirtueMart 3.2.4
Versão PHP: 5.6.35
Tixon Template - Joomshaper

I made the translation of the store into my native language (Pt-pt) and now the add popup box for the cart is confusing. Image attached. I needed to find the file to change the size of the box. Thank you
