8 – Duplicate results in view

I have a view on a D8 site displaying results of the content type “Projects”, sorted by the taxonomy “Project area”.

enter image description here

I’m getting duplicate results in my view output.

I’ve tried both setting the query settings to “Distinct”, and turning aggregation on, neither of which remove the duplicates.

Is there a solution to this? I’m not so great with Drupal so any simple explanations much appreciated.
