Hello,
I’m using X theme Version 5.2.5 (not Pro) and the latest WP Version 4.9.4 and have the following WPML plugins installed:

Since day 1 I’ve had problems with WPML. It took 3 months last year and a release before they could provide a fix to a bug I discovered (Element within Element not showing under Translations). Now re-launching and re-translating the website. The issues are back and the vast majority of all the elements from the EN default pages are not showing.
I too have the Translation Management for strings, which I don’t really need. Actually, I prefer to create dedicated pages, so I was extremely interested in @Rad’s post above. Video is simple to follow, but does the “Duplicate” work on the individual pages?

I have tried solving this issue over the past 2 days, so wanted to double check before I proceed.
The link & video submitted by @paul.r is not working and the WPML Support is very slow to react.
Appreciate your feedback.
Thanks
