My stencils are stuck

This is a fantastic app. I was having great fun right until my stencil got stuck in the upper right hand corner. Dont put the stencil there because you will never get it back. Will I pay for an app where I cannot rest any of my stencils. No I will not. Fix this issue immediately or give this app for free. Not worth paying for a glitch. Thanks!
