Corel Painter Essentials 5 lasso giving problems

So recently I have been having an issue with the lasso selection any time I make a pattern or design with the lasso instead of it making that design weather I delete the color or paint within the lasso area turns into a square, no I am not using the square selection I even tried it with the circle selection and it gives me a square. Is there any way to fix this if so how? I have been trying to color a commission for the past few days now and I updated to the new version and I am still having this problem. What can be causing it?
