Error with breadscrumb since last update

Since last update of wpsso-core I got some Structured Data errors as said by google tools on 16 pages. I don’t know why this page has been crawled as they are not in my index, but there actually have some troubles that I guess are related to wp-sso.

If I check these pages I got:

<script type="application/ld+json">{
    "@context": "http://schema.org",
    "@type": "BreadcrumbList",
    "itemListElement": [
        {
            "@type": "ListItem",
            "position": 1,
            "item": {
                "@id": "https://lemagcinema.fr/wp",
                "name": "Home"
            }
        },
        {
            "@type": "ListItem",
            "position": 2,
            "item": {
                "@id": {
                    "errors": {
                        "invalid_term": [
                            "Terme vide."
                        ]
                    },
                    "error_data": []
                },
                "name": null
            }
        }
    ]
}</script>

name null and errors in position 2 are the reason for google analysing critical problems …

How can I fix that behaviour ?
