Can't select confirmation page

[berlindave]

Hello experts,
I’m trying to setup a confirmation page for a form instead of a text message. but selecting a page is not possible, all pages are greyed out (see screenshot).

What could be the reason. What I am doing wrong?

For your hints many thanks in advance!
Best regards
David
