Mis-plotted geopolitical boundaries

In doing high-resolution (4km) WRF runs I've noticed that the
geopolitical boundary plotted for Great Britain is shifted eastward by
roughly 9 km from its actual location. This is confirmed by plotting
the WRF land-sea mask and noting it agrees with the true lat-lons of the
coastal boundary, whereas the geopolitical boundary does not. An
example for the Isle of Man can be viewed at

where land is in purple and the geopolitical boundary is the thick
dashed line (with model terrain the thin solid line) - but this is also
the case for the entire Great Britain mainland.

Is this a known problem? Is there a fix? I am using NCL version
