Breadcrumbs restart at checkout in custom WooCommerce purchasing process using direct checkout

I have made a custom WooCommerce shopping process using the WC direct checkout plug-in and custom add to cart anchor links which are around product images; see link example below.

<a href="http://localhost:45314/?add-to-cart=23"><img src=""/></a>

The customer chooses a size by means of clicking a normal anchor tag on a normal Wordpress page > The customer is navigated to another page with 4 images that if clicked add a product to the cart and navigate the customer direct to the checkout page > checkout.

This means that the purchasing process includes default Wordpress pages containing WC product add to cart shortcodes that go directly to the WooCommerce checkout.

So, I want the breadcrumbs to look like this on the checkout page:

Home > Choose Size > Monthly Plans > Checkout

The problem is that when I am on the Wordpress page part of the purchasing process the WC breadcrumb trail is fine, like this:

But, soon as I add a product to the cart which move the user directly to the checkout, the checkout page breadcrumbs miss out the previous trail and just start again from home; like this:

I’ve been looking into this over the past two days and the only solution I can find is to just add a permanent (not dynamic) breadcrumb trail on the pages or use the default WC cart process, which is out of the question.

Does anyone else have any suggestions please?
