The Data Anomalies page in Help has posted that Google has updated the structured data reports for Breadcrumbs and HowTo (in other words, breadcrumbs and step-by-step instructions) in Search Console.
Thus, Search Console has changed its approach to evaluating and reporting errors in Breadcrumbs and HowTo structured data. To view these changes, you need to go to the Advanced Results Status Report and select the appropriate section.
As a result of this update, new errors and warnings may appear in the reports, as well as changes in the severity of issues that have already been reported.
