shortcode works on Post but not in Portfolio

I used this shortcode [ssbp] on a post and it works
See:

But I also want it on my Portfolio pages but there it does not work.
See: https://www.poppinga.nl/en/onswerk/windzwaard/

You can see the shortcode after the text.
As you can see I have tried both versions, in both languages.

How to fix this?

Thanks,
