Is it just me, or does the M5 size of the pem self-clinching nuts have the wrong prefix?

The M5 hardware should be SS and CLSS, the same as the self-clinching nuts for size 10 of the inch series.

The size 10 in the inch series are identified correctly, is there a easy way to correct this in the configuration editor?
