Title, excerpt, featured image of related CPT not as an option?

Hi MetaBox,

I've created a CPT based on the Page and added some custom fields to it, besides using the title, excerpt and featured image. I've created a relationship from the Post type to this CPT. And now I want to show the values of this CPT at the bottom of the post. So I created an MB view. However, the insert field option shows the custom fields of the CPT, but not the default title, excerpt and featured image. How can I add those to the MB View?

To illustrate what I mean, I've created a screen recording: https://share.getcloudapp.com/2Nuq9Op5

Please advice, how I can resolve this. Thanks in advance for your time.

Kind regards, Henri
