Filter results displaying below product summary list

Just to add to the mix:

I had a situation where when filtering the products in a section the filtered results appeared below the list of product summaries rather than replacing them.

The Page design had originated in a Minimal theme and the layouts on the page were Section Page with name at the top, Product list with horizontal dividers, subsection list with horizontal dividers. Switching to the v12 default site's Section Page Bulk, Tabular product list, Tabular Subsection list fixed it instantly.

Using auto upgraded versions of old layouts can have problems. Using layout Section Page Body and other default layouts resolves the issues.

Thanks Louise. Hopefully this will save other users and Support staff yet more grey hairs!
