Webforms in Drupal 8

Dear Colleagues,

I was wondering if I could please ask you to help me with webforms.

I created two webforms, one to be used for internal users (RADIATION TEST REQUEST | CHARM), one to be used for external users (RADIATION TEST REQUEST | CHARM). The second one was created by duplicating the first one.

However, it seems that they are different in the edit modus. Furthermore, when I tried to add the link of the webform for external users to the main navigation menu (under Radiation Test Request https://charm.web.cern.ch/about-charm), the second webform is not found in the list where I can choose with page to be linked.

How can I solve this issue?

Thank you in advance for your time.

All the best,
