Trying to edit detail view

I’m tryig to edit the detailed view and see the below notification. Not sure what the notification means.

This DetailView is sync’d with the corresponding EditView.
Fields and field placement in this DetailView reflect the fields and field placement in the EditView.
Changes to the DetailView cannot be saved or deployed within this page. Make changes or un-sync the layouts in the EditView.

Just a guess here, but in your Edit View you probably have the “sync to details view” checked.

Have you tried to uncheck that and then try to commit your changes to the detailed view?
