Post linking to the same page

Hi
I am having issues with a page where I have a list of post and it keep linking to the first page I clicked.

When you click any investment, then go back to the page.
Then click another investment, it will link to the first investment. This repeats for other investments as well unless the user refreshes the page.

Please assist and advice.

Thank you
