User profil not editable

Hello UM experts,

after having tested multiple solutions in this forum I have still not found an answer to my question.

So I have activated Ultimate Member. When people come the site they can register with “Username, First Name, Last Name, E-mail”. This is for member of my organisation (fishing club) only so these are all the info I need to activate their accounts.

In the next step I wanted to active aditional fields on their profile like “favourite lake to fish”. I created a new form and linked this form to the Account page. In this form I inserted the fields “First Name” and “Last Name”. These are shown on the profile. (https://fischereiverein-guenzburg.de/user/test.test/)
I also added the fields “favourite lake to fish”, “favourite fish” and “Biography”. These fields are not shown anywhere.

I have no caching plug in installed.

The page I need help with: [log in to see the link]
