Make sure you cancel them from the downld window before removing from the incomplete folder. If they're video files then within the LW Library you can select the incomplete folder -> select that file & press Launch to see if it is 100%. This has often been a problem with larger video files. I've experienced it myself.
I believe the new
LW 4.11.2 Beta has overcome this issue. More about it here
