Order form not redirecting and processing payments

Hey there,
we are using Funnelish PayPal V2 app and Fancify for Clickfunnels. We have set up a multiproduct form with multiple variants.

We have set up webhook, funnels, actions, gateway, Stripe, PayPal products,… however, when testing the form keeps processing and do not redirect to PayPal.

We have also tested the Credit Card option and the same thing happens. It still keeps submitting and nothing happens.
