Product search WordPress admin not working

Hi there,

I’m trying to add up-selling and cross-selling products to my webshop. When I search a product inside the search field, it keeps saying “Looking for ‘charger'”, but doesn’t display any results. I only have 15 products, so I think this isn’t the problem.

Does anyone know what’s going wrong?

Thanks!
