With the L2P function, the other connectors (marked with red, in the attached image) were fetched properly from the 2D but the splices (marked with yellow) were not. I don't know why the splices were not fetched. I believe I have everything set correctly for the splices, also the electrical connectivity shows proper connections as well.
