Unfortunately, since I don’t really know what it is you’re trying to do and your site it in a language other than English, I really don’t know what the specific issue here is. Your issue is essentially localized.
It probably has little to do with Elementor and more to do with making sure you understand the plugin setup and/or integration.
The plugin’s default is to display a login and registration form in place of blocked content. For those that want a dedicated registration page, you can use the shortcode [wpmem_form register] (see: https://rocketgeek.com/plugins/wp-members/docs/shortcodes/form/#register).
If you’re making changes to fields in the plugin’s Fields tab and you use a cache plugin, make sure to clear your cache if you make any changes.
