Does anybody know why every time I am trying to delete a second name from a listbox, the previous name deleted reappear on the listbox?

I attached a VI. Just give it a try and you will see what I'm talking about. Try to delete every name one by one and you will see that the delete button is not working as it should. What am I doing wrong? I would appreciate it if you attach a VI. I'm more of a visual learner. Also, for your information, I'm new to LabView.
