You may need to switch the editor mode. You can manually do that on each post. For instance you can keep the editor mode set as you have it now, or at the top right of the post box, there is an a/A. If you click on that, it will give you the other editor. One of them allows you to change the display of the links and the other one doesn't. You can also permanently change the editor mode you use by going to your account preferences. I'm sorry that I don't know the correct name for any of the buttons. I am on someone else's computer and have to leave in 5 minutes. If you haven't responded to this by the time I get back to my computer, I'll try to be more specific with instructions then.
