part of object is unclickable

I'm making a game with drag and drop, but I have a problem. I'm using the drag and drop behavior, and it's working well except that only like half of the object surface is "clickable". You have to click on the top half of the hair in this case for it to work.

I know I can use an invisible sprite that is draggable and pin the hair to it, but it would be a lot easier if I could just do it this way and have the whole object be clickable.

Anyone have any idea on why it's doing this?

Set collision polygon

Set the collision shape for the image or frame. By default Construct 2 guesses a collision shape, but it is not always accurate. Click and drag the points of the collision polygon to alter its shape. Right-click to display a menu of additional options for the collision polygon, such as adding and deleting points.

wow thank you SO much, I had no idea that it guesses the collision shape! I just assumed that it's the same size as the png file. Thanks again!
