Background of the issue:
I am trying to correct the parent slug for three pages under my home page. The site map is set in WordPress, and each of these pages should have the parent page 'Home page'. I noticed that these pages have a non-existing Russian page '/obo-mne-rtt-gipnolog-2/' in their slug instead of '/home/'. This issue seemed to start after I purchased WPML and outsourced the website transfer from TranslatePress to WPML.
Symptoms:
The pages have a non-existing Russian page '/obo-mne-rtt-gipnolog-2/' in their slug instead of '/home/'.
Questions:
Why do the pages have a non-existing Russian page in their slug instead of '/home/'?
How can I correct the parent slug to show '/home/' instead of '/obo-mne-rtt-gipnolog-2/'?
