Before this ticket gets assigned to one of my colleagues, I will try to help.
Can you please let us know if you translated the content already?
Because, if the content was not translated already, seeing just one of the language flags (one language) at the top is something normal - it will just show the default language that you set inside WPML.
Please check if the page that you are looking at has been translated - or if the translation has been published and is not in "draft" mode or "under review".
