Why does different profile have separate tab names for same object?
When I log in to the Salesforce, I do see the knowledge base on tab as "Article" with link https://company--qa.cs14.my.salesforce.com/knowledge/knowledgeHome.apexp.
But when logged in as another user who has the same permission(when looking based on article) but on different profile does not have this link on the user tab. But I do see "Knowledge" on it with link https://company--qa.cs14.my.salesforce.com/_ui/knowledge/ui/KnowledgeHome They both show the same content but with different look and feel and layout.
I did checked the "tab name and labels" under setup > customize, but don't see any entry for this. Also I checked for any apex pages created for this, but don't see them too.
Any clue where this is set or where to look into?
