Hi,
The more results counter is based on an estimation, as the fully query is not executed for performance purposes, and there is a chance that the final number might be lower as the one displayed there.
On the General Options -> Limits page, make sure that the post type limit for the results page is also increased accordingly: https://i.imgur.com/3LzwOB9.png
This affects the number of results on the results page, regardless how much the ‘show more’ button shows, it will be limited to this number. The ‘distribute equally’ option might also affect this negatively with high numbers, it is a bit hard to predict, as it must run separate queries for each post type, then keep track of results to prevent duplicate objects.
Can you please give me an example query I can test for the duplicate events? I tried a few search phrases, but I can’t see any duplicates yet.
I see the theme has a ‘load more’ results feature on the results page. It is possible that it might be limited to certain number of pages only, although I cannot confirm that.
