How can I fix the back button redirecting to homepage instead of collection's first page?

[Gabi6]

Hello,

From the homepage I get to the collection page on the first page, then I get on the second page and when I push the browser's back page button, it doesnt gets me back on the first page of the collection, as it should but instead it gets me directly on the homepage.

What should I do to make the website get me back on the first page instead of the homepage?

Thank you!
