Not the svg its all in the fzp file. The difference is likely that the editor is setting both the description and the name field to the same thing and it then supresses one of them. Does it also manage to supress the internal label somehow (that is annoying but I don’t know of a way to get rid of it)? That is also a reason to have the pins in sequence since (due to a bug I expect) Fritzing will screw up the labels when the pins are not in sequence. It appears to assume the next number and labels it wrong then generally screws up the label on the next pin along before recovering.
