The messages in the set status message window is not getting deleted

Steps to reproduce:
1.Log into spark with user 201
2.On spark window, click on the drop down menu which shows the options for changing the status of the user
3.Set the status message for "Online" as : I am available and one more message as "I am free now". And similarly, set the status message for Away as "I am in a meeting"
4.Now click on edit custom message and delete all the status message set for online and Away and click on close
5.Now when you look back into the status message menu, it would have deleted only one message but the other two message will be still present.
And only that message is getting deleted which is deleted last.
