GAMON S620 keeps drawing even when I'm not pressing the pen tip?

Hi idk if the title explains my issue well. Normally when I press down on the tablet with the stylus it should register as me drawing and when i stop pressing down it should register me as not drawing. Recently its been going wonky with this and now draws even when I'm only hovering the stylus slightly above the tablet. Has anyone whos owned one of these have the same or at least similar issues? And if so is there a way to fix it?? I don't really want to spend more money to get a new one if this ones fixable since I've been saving my emergency money stash for more important things right now.
