Hi Alyssa,
What’s mentioned and shown here are for older versions https://wpml.org/theme/x/ only. Even WPML itself uses its own old WPML plugin on that one. I think the Multilingual Content Setup was also changed since that version, and maybe you’re missing a plugin that came along with the WPML plugin. Let’s check that from your thread with your provided URL and admin login credentials, make sure the credentials are added in the secure note to make it private.
The important part of this is a manual translation (not any translation, like string and advanced translation) else, it will not work, then you can either use the mentioned dialog or by clicking those + icons.
As for creating new thread, please go to forum https://theme.co/forum, select Support, and new topic button.
Thanks!
