Hi Shaun,
It looks like the problem is caused by the fact that the search in posts is enabled on the search settings, but the results page is can only display products seemingly. The empty spaces are actually post results, but they are not displayed.
If you don’t need to search in posts, just turn off the “Search in posts” option on the General Options -> Sources panel, and it hopefully solves the problem.
