Are you receiving notifications for someone with the same name as you? But it's not you?

You might of selected another player that is not you but has the same name.

Let's take a look and clean that up.

Click on the Menu (Bottom right corner)

Then the Settings icon (Top right)

Click on My events.  
Click on It's not me to the players that are not you or you didn't play in.
This will stop sending you the notifications that are not you and the stats that are not yours.

Look over your list. And if you have any events missing, search for them in the Unidentified Events.
