Clickers are dangerous. They can be either an aid or a crutch. I became what I call "clicker dependent" and was reacting to the clicker like Pavlov's dog. Click! Bang! The arrow was off. If used correctly, though, it should get you on your path to recover.
First, come to your anchor where it is most comfortable and where you feel you're in proper alignment. Have someone set the clicker at this point. However, it shouldn't actually click until you've gone through the expansion phase. So, ideally, you set, draw, anchor, expand through about 3mm, THEN it should click.
A really good exercise when using the clicker is to go through expansion so that it clicks but not release. Instead, let down and repeat.
