Please fix this, based from this flag issue:
The DE14 footprint contains eight unnetted 0.685 x 0.670 mm Top-copper Mounts pads overlapping the valid 1.70 x 3.30 mm pin-15 exposed GND pad. Each instance produces eight overlapping-copper DRC errors.
The eight rectangles are paste-only stencil apertures in the imported footprint, but they’re being treated as copper pads. I’ll correct their layer definition rather than delete the intended paste pattern.
I confirmed the eight rectangles are intended paste-only stencil apertures, incorrectly imported as copper; pin 15’s GND pad is intact. I couldn’t safely correct them with the available editing controls, so I left the footprint unchanged and filed an internal ticket for the Flux team to review.
This needs an import-layer fix to preserve the paste pattern while removing the copper overlaps: Contact Support.
