It will throw off the measurement.

you are trying to take the most accurate measurement of how much liquid you have in the burette. Even a bubble in the tip of the burette could throw off the measurement of what is really in the burette. Also, a bubble in the tip is not good for your lab technique because when you use a burette, you are dispensing the liquid by the drop. A bubble in the burette could force a stream of liquid out of the tip. This always happens when you just want a drop of liquid (lol) If you misdispense your liquid yo uoften have to start the experiment over so a bubble in the burette is not your friend...

Those air bubbles are taking up space. They will make your measuremet with the burette inaccurate.

As a matter of fact you could have it there... The problem is that it COULD escape during titration (one way, or another, i.e. down or up) and then the volume delivered would be smaller that the volume you think you delivered. So you want to eleiminate such possibility.
