Trouble with subscription user journey

I have some phenomenon within paywalled stories: If you click on the “Subscribe”-button portal/plans opens. But after entering an email and picking a subscritipon tier, new users are lead to email registration only instead of being forwarded to my connected Stripe offering.

So currently new user are not enabled to subscribe with us directly, first they will have to register their email.

Beviour on other ghost sites is different. If you meet a paywall there and choose a plan you will be redirected to Stripe directly (that’s also what I expect to happen).

Any ideas out there?
