Missing field item in breadcrumbs

Description

I require assistance resolving a technical issue afflicting the breadcrumb navigation on my WordPress site 1st4driving.co.uk. Presently, the Yoast SEO plugin utilized for generating breadcrumb trails is producing a 'missing field item in breadcrumbs' error message across numerous pages as documented within Google Search Console.
This breadcrumb malfunction has been thoroughly discussed online, yet despite exhaustive troubleshooting attempts, I've been unable to adequately diagnose the root cause or deploy a lasting fix. As the designated solution remains elusive, I am now seeking the expertise of a skilled WordPress developer to analyze the site, pinpoint the source of the error, and implement the necessary corrections.
In addition to remedying the current breadcrumb deficiency, ongoing support for this site as well as my two other properties may be required moving forward. Applicants should possess strong Proficiency with Yoast SEO, expertise navigating WordPress issues, and the ability to communicate progress clearly. Only candidates confident in their abilities to resolve even technical challenges expeditiously need apply. Once the specified breadcrumb repair is satisfactorily completed, the potential exists for retaining support services across all three of my websites.
