Welcome to Fritzing parts creation hell 
, over all not bad, but there are a few problems one of them (gerber generation) fatal.
I have fixed up both parts as new parts (varient2) so you can load both parts at once and made a test sketch in which I will point out the problems.

The comments below refer to this sketch (which contains both parts). Breadboard is by and large good as is, I chose to redo the scaling to make it match that recommended in the parts format document, but that isn’t user visible. I also changed the scale of the part from being width * height in px to width * height in inches, again no visible change but is more usual. The three data pins on both parts are connected to three pin headers and the power to single pin headers (doesn’t matter here but does in schematic). If we now switch to schematic, we start to see appearance problems (which don’t affect the operation of the part). You will see the wires connecting to your part are ending in the middle of the pin, that is because you don’t have the connectorxterminal rectangles defined in the schematic svg (they are in the fzp file). On this part (the GY273) you will see the order of the pins differs between breadboard and schematic, again an appearance issue, not functional. Pcb view in fritzing looks fine, but when you generate gerbers (such as to cut a pcb) things are fatally wrong. This is the gerbv (a gerber viewer) output of the pcb view as a gerber:
The part on the left in each pair is my corrected version, your two from the original parts are scaled incorrectly and don’t connect correctly (likely because of translates in the pcb svg although I didn’t check). While both new parts will be in the temp bin of the test sketch above, I will upload a copy of the fixed parts to both these parts so people coming along later can just grab the corrected part. If when you look at the svgs of the new part you can’t figure out what I did, feel free to ask, the more people making parts the better as far as I’m concerned
