Google search result titles duplicated

Hi, I recently published a new project:

This is a website for a law firm studio done in double language (duplicating the pages)
I’m having some weird Google search results, and have not been able to understand why is this happening. Basically the google results for the home page show me some duplicated title results.
I’ve tried everything on google search console and webflow, and discussed this with other developers and no one seems to understand what is wrong. @Vincent can you please help me on this one. Anyone any guidance much appreciated in advance.
