Thank you for contacting WPML support. While you are waiting for one of my colleagues to take this ticket and work on it, let me provide you with first debugging steps or if I can perhaps help with the issue quickly.
For a page that is stuck in progress, please test these steps on one of the pages to see if this resolves it.
1. Go to WPML -> Translation Management -> Translation Jobs and cancel the in progress job. If there is no in progress job, continue to the next steps.
2. Edit the default page. Make any small change and update the page.
3. Go to WPML -> Translation Management and send this page to the translation basket. Tick the checkbox, scroll down and click translate, then you will see the translation basket tab.
4. Click the translation basket and send the page to yourself as a translator.
5. Go to WPML -> Translations and take and translate the page. Save the translation 100% and then let's see if the correct content shows.
