Conflict in Breadcrumbs: Yoast vs. Custom Coded JSON

Hi!

I have Yoast SEO installed, but I code my own breadcrumbs using the JSON method.

In the SERP, my breadcrumbs display a very strange behavior: it stops at the parent page (which is a custom taxonomy in my case).

For instance, for the page: example.com/kitchen/coffee-makers/
– Expected result : example.com › Kitchen › Coffee Makers
– Actual result : example.com › Kitchen

For the page example.com/kitchen/coffee-makers/keurig,
– Expected result : example.com › Kitchen › Coffee Makers > Keurig
– Actual result : example.com › Kitchen › Coffee Makers

I checked my JSON coding but found no error. Two questions:
– Could it be that Yoast’s breadcrumbs take priority over mine in the SERPs?
– Could it be that Yoast’s breadcrumbs cause an error with custom taxonomies?

Thank you!
