Why is the my 1920x3 rectangle not exporting?
Hello, I'm adding little touches to my web design project and was wondering why a rectangle of 1920x3 aligned to the top most of the artboard not exporting?
Here's what I mean


The first one is where the rectangle tool is aligned to the top.
I tried moving the rectangle a bit downwards and it exported.
In the desktop preview, I can clearly see the line, when I export it to a png file, it doesn't.
What seems to be the problem here? I'm sure my layers are stacked properly.
