Hello all, working in RVT2010.

 Been having the same problem with stairs lately.  The balusters/pickets work fine, until I get to the top of a stair run and hit an intermediate landing.  The raining adjusts for this and levels out, but for some reason, the bottoms of the balusters/pickets continue upward, as if the stringer was still going up.

Any idea what the problem is???

Please see attached image.  Don't worry about the other problems (yet).  I haven't addressed them in the model.

Thanks for your help!

(Also, in case you might miss it, take a look at the outside balusters as they continue on the lower landing....)
