I'm not sure if it's the issue, but open up the layer dropdown menu, then open add new linework layer. I prefer using the curve tool and cutting it off (I do so by pressing the selection tool, then going back) so it doesn't get too curvy, but I also make use of the edit tool, which allows you to make new points in any line, and adjust it how you like (like if it looks too bumpy, or your lines aren't clean on the ends). By using the edit tool, you can even free draw and select those iffy points to make it look just right.
