Translate and Adapt - Widget doesn't seem to work and how to customize the look & feel

[Manggo]

Hi,

My shop is manggo-skincare.com (no password). I have just downloaded the Translate and Adapt app from Shopify. I have two languages published - English and Spanish. And I'm facing the following issues:

- The widget doesn't work, I try to change to Spanish and it doesn't do anything

- It changes completely the aspect of the header - it adds this weird arrow and a border to my header - how can I customize this?

- besides that I am also trying to translate to Portuguese but I cannot add this language to the Portuguese market.
