LaneFromTaperedMedian2 - assign profile to right lane

[oageng09]

Hi, 

I am building a dual carriageway, 

I have assigned a left alignment and vertical profile to to my corridor following the LaneFromTaperedMedian2 assembly. On the right, the assembly targets the right hand side alignment, only horizontally. 

How then do I assign a profile to the right alignment? In the picture the right carriageway is much higher than the left. I have tried placing an assembly offset on the right but it does not pick up the right profile. 

I essentially don't know what profile the right carriageway follows, it is too high. 

And why is the median sloping up when I did not design the assembly with a slope?
