[مغلق] Want to retain english slugs, when translating to chinese

Background of the issue:
We are in the process of finalising translations to Chinese. We noticed an issue with the slugs translating - we want to keep these as english please.
We also have an issue that is maybe related. The Chinese translated pages sometimes redirect to the wrong url and return 404
for example: (الرابط المخفي)

Finally we have an issue with some of our 'tags' not showing in the translated pages (see image attached)

Symptoms:

Questions:
Can you let me know what has happened with the slugs and how to keep them in english even on the chinese pages?
And if this fix is related to the 404s.

And finally why some tags are not showing but some are..
