Did you edit with an text editor or inside gschem?

Your initial DIP28 contains lines like

Pin[-15000 -65000 6000 2000 6600 3200 "1" "1" "square"]
Pad[-17500 -65000 -12500 -65000 6000 2000 6600 "1" "1""onsolder,square"]
Pad[-17500 -65000 -12500 -65000 6000 2000 6600 "1" "1" "square"]

This is a pin with name/number 1 -- the two Pad statements are used to
overlay the plain round pin with pads, one on solder side, one on the
other side -- I guess to make the pin copper oval. For plain round pins
you do not need the additional pad statements.

For your modified version you seems to have removed some Pin statements,
but not the corresponding Pad Statements.

I suggest reading
