I believe there is a small issue when using Elements and the display rules.
Let’s say you have a CPT : Product – You don’t want an archive page for this CPT (cf. has_archive = false)
Then you attach a Custom Taxonomy : product_cat
–> You are unable to find the archive for the custom taxonomy in the display rules. In order to see it, you need to change has_archive to true for the CPT. But it doesn’t make sense as you can have has_archive = false for the CPT but you still have archive for the custom tax.
