CPT posts are not showing up in the taxonmy URL

Hi,

The website posts has created many tags. Then I created a Custom Post Type and add a CPT post uses a tag that ordinary posts used.

The backend shows that the tag has 2 posts

But when I click on the tag at frontend, only 1 post (the ordinary post) shows up.

The CPT post with the same tag didn't show up

Here is the link listing CPT post

Thank you.

Hi,

I was told by the Oxygen team that this is a wordpress oddity...

Anyway, there's a way in CPTUI that I can add the custom post types to the default category and taxonomy archives.

Is there anything similar that I can do in Meta Box?

Thank you.
