I'm not sure I know exactly what you mean here, but I don't think English is your first language so I'll try to help in a simple way
When you say "under your name" do you mean this?
If so, those are not your messages. That is just the number of times that you have posted on the forum. Our system keeps track of that number for you. Don't worry about it. As you can see, I have almost 1,500. You can see this number for any user, and it just means that this is how many times they post something on this website.
Your personal messages will show up here:
And here:
If there is a number there other than 0, it means you have a new message.
Now I'm not certain I solved the problem you actually needed help with, feel free to explain more if I did not and I will try to help you out.
