This might be issue on JLCPCB side, their preview rendering had failed me on more complex boards in the past. When I removed most vias from that Gerber files or KiCad project that generated them, preview started to work. When I finally ordered boards design (with all the vias) they came all right, it was just preview stage that was failing
It was 2 years ago, JLC might have improved it or not.
