Dawn 8 Theme. Identical collections on every collections pagination

Hi there!

I recently updated my website’s Dawn theme from version 2 to version 8. However, I am facing an issue with the collections page paginations. Prior to the update, all of my collections were displayed on a single “collections” page. However, after the update, the collections have been split into 15 pages, but all of these pages are identical to the first page where all of my collections are listed.

Can anyone assist me with this problem?
