Your screenshots do not provide enough information. Therefore, the following is based on guesswork only. It is not clear exactly what your "part" comprises because it looks like the through holes along the edges also move. If the part you are trying to flip is a library part then please post the link to it from: [https://easyeda.com/components?docType=package](https://easyeda.com/components?docType=package) Is the shield outline shown in your screenshots a PCB Footprint, a PCB or a PCB Module? In any case, please post a link to it as a public Project (i.e. including the schematic from which it was generated).

@andyfierman Here's the location of a new public project with the troublesome UNO in place: [https://easyeda.com/icecool2/sample-pcb-project](https://easyeda.com/icecool2/sample-pcb-project) This is a library part that I'm using. The outline shown is the footprint of an Arduino Uno as it would sit on the larger PCB.

In your screenshot you had a J4. Where is J4 in your schematic? The UNO\_R3\_SHIELD appears to have no silkscreen outline so it is not obvious what happen when you move it from top to bottom layer\. However this has shown up another problem, not with the way it is constructed but with the way EasyEDA handles the way it is constructed. Please see: [https://easyeda.com/forum/topic/Document-layer-does-not-swap-from-top-to-bottom-layer-with-the-rest-of-the-footprint-50976e7140764fffb4cecb560a2d37aa](https://easyeda.com/forum/topic/Document-layer-does-not-swap-from-top-to-bottom-layer-with-the-rest-of-the-footprint-50976e7140764fffb4cecb560a2d37aa)

@andyfierman The J4 was a separate connector. There wasn't a library that had the ISP pins so I just quickly through that in there. I guess at least it wasn't me doing something wrong, rather a bug. Thanks for posting the bug report.
