Both the plug and jack parts in your example Fritzing sketch have a typo in the connector terminal ids.
For the jack, the part fzp file says
layer="breadboard" svgId="connector3pin" terminalId="connector3terminal"
but the breadboard svg says
id="connecotr3terminal"
For the plug, the part fxp file says
layer="schematic" terminalId="connector1terminal"
but the schematic svg says
id="connecotr1terminal"
"ot" should be "to" in both svg file cases.
