Shopify Search & Discovery

All of my recommended products on every product in my store was reset to some random default with no warning, giving me hours if not weeks of work to do. Editing to now mention that changes to the recommended products are not sticking. The app is showing random products in the recommended section and there is no way to edit it. This is really, really frustrating. I've been wondering why sales have been down the last few days, now I know why. The "hide default" products is not working.
