Profile page only shows header, content don’t display

Hello thanks for the great plugin, I am having a challenge. I am using a custom made child theme based on https://underscores.me/
We use the following plugins: Event Manager, AntispamBee, Wordfence, Rich Reviews and of course Ultimate Members.

I believe we have configured things right, we have 2 forms for 2 different profiles: “talent” and “ouder” we have put both shortcodes in the default user profile page created by Ultimate Memeber. For unknown reason the profile page only shows the content of the header and does not show the content of the full profile, below the header.
Any adivice and help is very welcome. Thanks!
