No, it is just telling you that it has what it thinks is an old part (instead of one that we have screwed with to do what we want). It can be ignored, although your part won’t correctly change to the bottom of the board due to this, you likely won’t care.
Your fatal problem is the fzp file is incorrect, you only have copper1 and thus only have pads on one side of the board. Secondary problems (but can be ignored) are incomplete schematic or breadboard views. In addition the pads from top to bottom are offset in y which may not be correct as this image from the gerbv geber viewer demonstrates (with a corrected fzp file). Purple is bottom layer orange is top layer
If you have the data sheet for the connector I can fix this up for you if you like. This part contains the corrected fzp file which generates the above gerber output (I was too lazy to make a new part so you will need to remove your current part and restart fritzing to load this)
