I’ve already created a ticket in the support forum, but it has gone unanswered for almost 2 weeks now. I’ve even followed up with comments to help identify the issue.
https://ww.wp.xz.cn/support/topic/bug-bundled-product-page-appearing-in-wrong-products/
It appears in the code that matches bundled products based on how it is stored in meta, it uses id + “/” with “LIKE” queries, causing the bundle id to match if the product ends with a similar id.
So product id 23 will display a bundle with product id 123, when the bundle is stored as 123/456/789/
