If I create simple PCB like this
[https://easyeda\.com/editor\#id=\|75bb61f607fc455585a8426adbb37277](https://easyeda.com/editor#id=|75bb61f607fc455585a8426adbb37277)
with 2 via holes in the middle and later I export it to
gerberfile.

When I try to preview it in
gerberviewer
[http://www.gerber-viewer.com/](http://www.gerber-viewer.com/)
or try to make an order on [https://jlcpcb.com/](https://jlcpcb.com/)
and preview, it looks different (like this).

both gerber viewer mentioned above show something strange in the left bottom corner,
what does not exist in easyeda editor and what I did not put. Is it bug of easyeda
or bug of those veiwers?
