Fixed board edge and position of 3.5 mm jack
...
The 3.5 mm jack footprint from the standard KiCAD library had to be
modified. The PCB edge was moved 0.85 mm outward to match the C62
connector and PCB layout.

Added modified footprint for the PJ-204 audio 2.5 mm jack
...
This alternative footprint does not have three mounting mechanical
holes. This will make the jack body 0.5 mm higher, making it better
aligned with the center of the 3.5 mm jack.
