Eraser tool is leaving a weird mark on my project
Hi,
I just got a Wacom tablet and was using it on one of my projects. When I try to use the eraser on the pen, it leaves a weird bubble mark where the eraser was used. So I tried the eraser tool to see if it was just my tablet acting up. When I use the eraser tool it does the same thing. I made sure that none of my shapes had a fill color and its worked fine before so I don't know what to do. I've attached pictures to illustrate my problem. The first is when I use the Wacom eraser and the second is when I use the eraser tool in AI. Please help!
