Incorrect breadcrumbs displaying

I went into the product itself and it doesn't look like the category that is displayed in breadcrumbs is actually checked in the category list.

Here is another example:

Hi there,

I don't believe this is a GP issue as the theme doesn't interfere with breadcrumbs from third-party plugins.

Can you try #4 here to test first?

I'm also unable to view the issue as a username and password are required for viewing access - I believe it's a different set of credentials from the admin access provided.

In checking, the problem still existed. However, I noticed that the Brands (product_brand) taxonomy isn't available and I was wondering if there is a way to enable it. That seems to be the difference so far between my old theme and GP

That is not something the theme would add or not add.

Sounds like you are looking for a WooCommerce setting?

That's what I thought initially but the problem goes away when reverting back to my old theme, which supported product brands.

Perhaps your old theme added some custom function for it.

This is definitely not something the theme can control by default - you should see the same behaviour when testing with a Twenty series WP theme.
