Halos with Apple Pencil

I opened up a painting I've worked on for some time.  Now when I touch my Apple Pencil to the iPad screen there is a double colored halo that radiates out from the point of contact with the screen.  I'm using a GoGo digital brush.  I get the same halos using a water color or vector option.  I would very much like to be rid of these halos / double concentrict circles.  Help!
