I checked with a different PCB with all components on top side and that placed everything correctly.

This is the one with the components on bottom side and data NOT flipped 

@MikeDB Hello Mike ; Our engineers will handle your production files so there will be no mess in the produced board, the viewer is not a 100% reference to what it looks the final produced board. You can use our online component placement editor to fix the components placements and orientation. please check this thread where I explained how to activate the Beta view for the online editor and how to properly use it :  [https://easyeda.com/forum/topic/SMT-Assembly-Wrong-components-placement-a8d4fb943cf340eeb9309faca7340b23](https://easyeda.com/forum/topic/SMT-Assembly-Wrong-components-placement-a8d4fb943cf340eeb9309faca7340b23)<br> <br>

@JLCPCBsupport   Rather than have a online placement editor, shouldn't EasyEDA get the placement and orientation correct in the first place ?

@MikeDB Yes because the CPL and is generated by the design tool depending on the design parameters. Maybe @andyfierman  could provide some tips on this purpose.

@JLCPCBsupport  @andyfierman I don't see Andy being able to fix this problem.  The EasyEDA software appears to have a serious bug in it which needs fixing.
