Actually for me none of them are on the grid 
, I haven’t found a way to make it fit to the grid even moving the .1 connectors in Inkscape by what I think should be a correct offset to put them on the grid (I don’t really care about the 2mm ones because they won’t fit a.1 grid). It seems to move the pins in an non linear fashion so that doesn’t work. One thing I notice is both parts lack a breadboard layerId which means that they won’t export from Fritzing as an svg (you need to select all, group and name the group breadboard to fix this). In schematic on the xbee_usb_mini_adapter I prefer to set the pins to be the same as the breadboard, in this case pin 1 (connector 0) would be on the bottom right instead of the top left as now and the .1 connectors would be on the bottom and all 5 of them present so the schematic will match what breadboard really looks like, but as usual that is just me, and your part your choice! As usual good job on breadboard!
