That type of problem is indicative of poor circuit reference conductor
routing (colloquially called "ground loop" or "pin 1 problem") and can
sometimes be improved with judicious use of added wire or copper foil tape
connections, but often requires a new and proper PCB layout to correct.
It is basically just sloppy layout work by the design team.
