I have about 800 pages on my site, and about 150 of them are Custom Post Types made with Metabox.
Breadcrumbs work fine on the rest of the site, following the proper structure home>page>sub page and worked on these pages with the exact same URL structure and urls BEFORE I turned them into custom post types.
Now, as a custom post type home>customposttype>customposttypesub breadcrumbs appear as home>customposttypesub.
It skips the parent page entirely in the breadcrumb. It's wrong. My breadcrumbs are supplied by RankMath - everything works perfectly there and everywhere else. It MUST be custom post type related, please do not pass this off to RankMath - I tried.
Please, let me know why custom post types would skip the parent page in breadcrumbs.
