Search Results Page content missing products

Hello,

we are using the feature of showing a search results page when a user hits the enter button of a search.
The problem is that not all for the search string relevant products are shown on the search results page. But in the AJAX results they are all shown. Also the layout of the search results page is messed up, not showing the correct amount of products per page that is displayed. Example: Site says “Showing 10 search results” but only 3 are actually shown (too less).
Setting $enabled on ‘false’ for the function aws_searchpage_enabled( $query ) in class-aws-search-page.php solved the problem. But then the search results page misses AWS features such as searching for SKU.

Any ideas on how else this could be solved? Reindexing the table and clearing cache unfortunately didn’t help.

Best regards,
