Mailbox problem

In the extra top menu where you have notifications, its telling me I have 6 messages in my inbox but when I go to my inbox its empty. D7.1

The Inbox

Please could you provide more information on how to reproduce this problem ?

Hi Alex,

I did some searching around and the problem seems to be coming from a module called Game Zone that I purchased. Messages are being sent to a users account when a game battle starts but when the message is deleted, it is not being removed from sys_messages for some reason. This isn't a core problem I don't think so i'll try to figure it out. Thank You

Thank you for the clarification.
