Protected content message isn't showing for the correct membership?

Greetings!

I have set up a membership that isn't publicly accessible called "Coming Soon".
This is in effort to "hide" pages that are coming soon (maintenance pages).

The protection rules work fine, although I'm not sure how to apply a custom (not default) protected content message to those pages that are protected by the "Coming Soon" membership.

In screenshot 1 I have set the Membership's (coming soon) to define a custom protection message (not the default one). However when I visit a page that is only protected by the coming soon membership I am given the default protected content message (brought to protected content page). You can see that in screenshot 2.

How can I apply the custom protection message to the pages protected by the Coming Soon membership?

Also, support access is granted!

Thank you and much love!
