Lines duplicate and delete others

I just downloaded Pencil2d and when I draw a line and move it, it copy’s and messes up my artwork. also, when I put a line close to another line, it partially deletes the other line… I can’t make a video with these problems happening, and need this fixed please.

  1. The duplicate glitch (that’s what I call it) - Can be fixed by (after select it) copy it (ctrl + C), click the button that looks like scraped up paper (or just erase the drawing) and then paste it (ctrl + V).

  2. The line thing, I’ve never seen that glitch before. I pretty sure you’re using the vector layer. The vector layer can be glitchy. So I recommend you to use the bitmap layer only.
