Required customizable options not keeping quantity from catalog to product view

When I have a product configured with required customizable options the page is redirect to the product page letting the customer know them must select a required option. This is fine.

The problem is from the catalog view I enter x for quantity and when the page is redirected to the product view the quantity now shows as 1.

The quantity should be carried over from the catalog view to the product view even if there are required customizable options.

I checked the request and the quantity data is not there?

What is the best way to get the quantity entered from the catalog view to the product view when redirected because of customizable options?

Magento version 2.2.7 with Porto Theme

Any help would be great!
