Hi Vani,
If fr is the live copy of en master, then we should see 'cq:LiveSyncConfig' node present under fr/jcr:content level, then only you can see Live Copy tab in the page properties.
I'm not sure how 'cq:LiveSyncConfig' is missing at fr Live copy level.
1. you can check on other live copies and see how it works? this gives an idea whether it's an issue with particular locale or something wrong with your instance/live copy creation itself.
2. Also, please share the AEM version you're using.
