After upgrading to 9.3.5, we've experienced a bug with multiple repositories. The frontend gives us the following error:
System.IndexOutOfRangeException: Index was outside the bounds of the array. at Dynamicweb.Ecommerce.Frontend.Frontend.GetProductsFromIndexQuery()
Our top repository seems to look at the wrong query when creating facets.

The screendump shows that both queries are selected, so this might be why it looks at the last query.
