I'm having problems with the conditional display rules within a template drop. I've created a template for a dual carriageway with slip road tapers on each side. I've set the display rule that the slip road lanes will be displayed when the slip road is present, and to hide the mainline hard strip/verge/earthworks. However the trimming seems to go wrong when I do my template drops. At station 209+820 the eastbound slip road ends taper ends, but the display rule is killing off the components and linear features within the next template drop at this station.
