Line disappears when connected to other lines

[jeremy30420424n2ts]

whenever I am drawing, if the line i am drawing connects to another line, which I had already drawn, once i lift my pen up, it disappears. for example, I would be drawing a table, and when i try to draw the leg of the table, once the line connects, it disappares.
