In very rare cases, you might see two sets of breadcrumbs on single product pages due to a bug. This is the case if you: - install WooCommerce 7.9.0 from scratch (so: not upgrading an existing store); - and you use a block-based theme (such as Twenty Twenty-Three); - and you use Yoast SEO for WooCommerce with the option Replace WooCommerce breadcrumbs set to on (as is by default). There are two ways to work around this problem: 1. Set Replace WooCommerce breadcrumbs to off and just stick to the WooCommerce breadcrumbs. 2. Set Replace WooCommerce breadcrumbs to off. Then, visit Appearance > Editor, find the Single product template, and replace the Store breadcrumbs block with the Yoast SEO breadcrumbs block.
