Yoast SEO breadcrumbs missing ListItem name and adding #webpage at the end of the URL

I am using Yoast SEO. Our SEO tool is showing an error that we can't seem to fix through the configuration options.

A value for the name field is required

Apart from the 'missing' name field, Yoast SEO seems to add a #webpage anchor link at the end of the URL. Here is the json-ld output of one of the pages:

{
    "@type": "BreadcrumbList",
    "@id": "https://testsite.com/international/#breadcrumb",
    "itemListElement": [{
        "@type": "ListItem",
        "position": 1,
        "item": {
            "@type": "WebPage",
            "@id": "https://testsite.com/",
            "url": "https://testsite.com/",
            "name": "Home"
        }
    }, {
        "@type": "ListItem",
        "position": 2,
        "item": {
            "@id": "https://testsite.com/international/#webpage"
        }
    }]
}

Is there a way to manually or programmatically add a name to the last ListItem?

And is there a way to remove the #webpage at the end of the URL?

Thanks
