Product Display Limit

I have a WooCommerce store with about 5,000 products and even after filtering to items with ending in specific titles, I can never get Bulky to show all possible results. I’ve set the products per page to 100 and sometimes I get up to 600, while other times I just get a single page of 100 with no option to load more pages. Is there a max product limit or some other reason for this, and is so, is there a way around it?
