Hello @phoenixoracle,
Thanks for reaching out about your breadcrumbs structured data. I also got the error you mentioned when I ran that URL through Google’s rich results test tool. However, the error is not coming from the Yoast SEO plugin. Another plugin or your theme is likely responsible for the duplicate/incomplete breadcrumbs structured data – https://tinyurl.com/2xglo3dr
The Yoast SEO output starts with <script type="application/ld+json" class="yoast-schema-graph"> on line 29 while the conflicting out is on line 130.
Often, we see problems occur in combination with another plugin or theme. The fastest way to rule out any conflict is to deactivate all non-Yoast plugins and switch to a standard theme like Twenty Twenty-Two.
Please test this on your development or staging site if you have one. If not, we recommend using the Health Check & Troubleshooting plugin. This plugin has a troubleshooting mode, which does not affect normal visitors to your site.
If you’re unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process: How to check for plugin conflicts
If you feel uncomfortable doing this yourself or if this does not solve your issue, our Yoast SEO Premium plugin comes with one year of (technical) support.
