After ruling out custom code and digging through documentation, I discovered this behaviour is actually an undocumented feature that has existed for years. In this post, I walk through the debugging process and share a simple initialization module workaround to prevent category inheritance. https://reillydom.com/blog/optimizely-cms-12-category-inheritance-undocumented-feature Fri, 20 Mar 2026 14:30:00 GMT Blog post
