Hi
this PCB looks incorrect. it has two coppers at inner layer but can't find at the canvas?
How do you create this PCB? what should I do to repeat this issue?

Thanks

I made from these 2 PCB: https://easyeda.com/editor#id=56c8def8e2ed4ff7bbd3c9cd5a272d8c|7c49fcf535af484581682e610814a89f

but in your picture the right-up  pictures like as these PCBs : https://easyeda.com/editor#id=99ed61ed855e4d60875257c88f555204|dbf1ac51455246d581e90cedd7b0a2d1

These PCBs are in my other order

Please enable the inner layers at layer manager, and Setting, and then disable the inner and setting, this PCB will be fixed.

How to make? any details?
that looks is a bug. we need to repeat it and fix it

Thanks

And Sorry I don't know how I did this :( :(.

When I finished the projects, (4 piece of PCBs).  I tried to minimalize the cost, so I had to put more PCBs in one Boardoutline,  and the board size had to lower than 102mm*102mm. So I tried some combinations until I made 2 PCB from 4PCB. But now in Easy Eda I just see 2 PCB in 1 Board outline, and that's correct. So what you see it can be a previous version. Which you can't see in EasyEda, because I have deleted(but perhaps not in the correct way). But you see in your program.

@UserSupport

And what is your program, because  I can't see  the difference between correct or incorrect file in Eeasy Eda, these are the same in Easy Eda
