How to hide "Details, Legislative Information and additional information" on self service page?

Summary:

On the self service page to add absence are the sections Details, Legislative Information and additional information shown, even though there is no information included.

In the absence types I disabled all the settings, which would be required to those sections.

In Design Studio I'm not able to hide those sections and also via Page composer I was not able to hide them.
