Okay, that looks right.
I see you have the index table engine selected – that could explain the issue.
If the products are not indexed, then it will still yield no results. Basically there is a single index, and you can create as many different search instances as you need. Each of them can be configured differently, so in the index you can have many many different post types, while separate search bars can be set to search only a subset of them.
Can you please make sure that the products are also indexed: https://i.imgur.com/sHCN1mG.png
That will very likely solve the issue.
