The word Profile you're seeing in the upper right corner indicates that you're logged in your profile page and it's not your actual Display name. Every user sees this.
You'd be able to see your Display name on the mobile app, for example.
If you can't find yourself in the Search option, this means that there are most likely multiple other users with the same Display name. To improve visibility make sure your app is not set to Private Session. ( Settings > Social > Private session should be switched OFF; Listening Activity should be switched ON)
Let us know what Display name you see in the app itself and if it's the one you've set for yourself.
