[Resolved] translated page with same title not displaying

Background of the issue:
I am trying to translate my pages, but two of them, faq and supervision, have the same title in EN and FR. I turned on the manually translate URL setting, but do not see this in the translation editor. I deleted the translation, made a fresh edit on the default language (EN) page, and when I go to create a fresh translation, the translate slug/url field is not there. I think it is flashing on for a brief second though. Link to a page where the issue can be seen: hidden link

Symptoms:
Page not found error

Questions:
Why is the translate slug/url field not appearing in the translation editor?
How can I resolve the 'Page not found' error for the translated page?
