Schema Deprecated

I got a message from Google Search Console today saying there was a new breadcrumbs issue detected on my site. When I logged into the search console it showed a warning that schema is now deprecated. Is the default CS-Cart responsible for this, or would this be coming from an Add On like SEO Ultimate from CS-CartRocks?

Any help appreciated.

No one else getting this message from Google Search Console?

Yup I'm getting it as well.

And dunno if this makes sense

when I run the structured data test I dont get breadcrumb warnings , I dont use 3rd party seo plug ins

Thanks John. So this would seem to confirm that this is coming from an add-on, not the default CS-Cart setup.
