Please check your Gerber files using gerbv: [https://docs.easyeda.com/en/Export/Export-Gerber-Files/index.html#Gerber-View](https://docs.easyeda.com/en/Export/Export-Gerber-Files/index.html#Gerber-View) If they are ok in gerbv then they will be good for manufacturing by JLCPCB.

@andyfierman I have checked in the given link already, also verified with other viewer called "circuit people" but same result. The gerber generated in previous version doesn't have this issue. Below is the snapshot of the issue. 

hi don't worry, it will not impact your PCB manufacture, it only photo view issue. at v6.1, we will change this copper area.

@UserSupport Thanks for the reply.
