This is probably air in your brush. You need to make sure that you remove the air in your brush before picking up your powder. Place the brush in the liquid and twirl it between your fingers, you should see small bubbles appearing, swipe the brush, once as you remove it and you should be ok. If I were you I would contact your trainer, they are all friendly and will be happy to help.
