ADE taxi route issues

Hi all. I'm trying to edit an airport which has unrealistic taxi routes given by ATC; i.e, when at gate, ATC will order to taxi via the opposite runway (backtracking) instead of taxing on the taxi way. So I open up the airport in ADE (it's an add-on airport, so I'm importing the bgl and then re-compiling, if that makes a difference).
First thing I tried was "closing" the taxipath on the runway itself. That didn't work, so then I deleted the taxipath (there is nothing on the runway now in ADE). But still, ATC persists it makes more sense to taxi on the opposite runway and messing the traffic flow at the airport rather than simply taxing on the taxi way

Sorry if the post didn't make sense and I'd be glad to post screenshots from ADE if that would be necessery.
