Save button does not work in Creatio 8.0 on an application created with the application hub

Hey there,

I've created a new application on Creatio 8.0 with a simple object that only has a lookup to a contact object. When I save a new record "Candidat", nothing happens even though it seems to be correctly configured.

How can I solve this problem?

Here is a video showing what's happening : https://youtu.be/U7QlUvOBVaQ

Kind regards,
