Should a confirmation-before-submitting page on a form contain all the information a user has entered?

I'm working on a product with a long, single-page form.

This form contains between 18 and 32 (these numbers may change in the future) fields -- this number depends on the version of the form the user selects.

A feature we are building is a page after the user fills out this form and presses "continue", to have the user review the details they entered on the previous page to make sure that information is accurate before they submit.

Previously, this page only showed key pieces of information. However, I'm considering showing all of the information that the user entered on the previous screen instead.

Does it seem weird to only show parts of the form's details?

Additionally, is it too repetitive to show all the fields a user recently input on the very next page?
