Taxiway lines at taxiway intersections

The image shows my problem. The left one is from a satellite image, showing the current layout of the lines. The right one is how the lines are drawn by ADE. Is there any way to easily get rid of the lines going in the wrong direction (pointed out by the red arrows)? I suppose that the circled numbers have to be done as ground polys, but will the the ADE taxilines show on top of the ground poly? How should one tackle that? Do I have to make all the lines as ground polys?

EDIT: Actually, now I found the solution to the intersection problem by chance. I moved a taxiway point somewhat and the redundant line disappeared! So it seems that the precise placement of the connecting points is crucial. I still have to understand how to make the more complicated intersections look right and how to make the circled numbers.
