Adament theme – adding 2 portfolio instances

Hello,

I’m working on a real estate agent website and I’m using Adament theme {found here}

The problem is, I need 2 Portfolio instances, one on “For Sale” page and another on “For Rent” page. I’ve created two different template pages “rent-pages.php” and “sale-pages.php” instead of the original called “portfolio-pages.php”, and I’ve assigned those templates to their respective pages, however no matter what I do all items added to the Portfolio section appear only on one of them.

Is there a possibility for solving this issue?

Thank you in advance
