create RailingType:cannot set the heigt of NonContinuousRailInfo

[506988194]

Steps to reproduce
When I was trying to create a RailingType,I got two problems.
1.when creating the RailStructure(NonContinuousRailStructure) of the RailingType,seting the height of NonContinuousRailStructure,I got an error:Autodesk.Revit.Exceptions.ArgumentException:“The height height is not valid for the non-continuous rail.
2.when creating BalusterInfo and setting the BalusterFamilyId,there is a BalusterInfo from the RailingType copy source,which I can set it's BalusterFamilyId,but when I set the BalusterFamilyId of the copy，I got an error like: Autodesk.Revit.Exceptions.ArgumentException:“The balusterFamilyId doesn't refer to a valid baluster family.

Expected results
The height of NonContinuousRailStructure changed to 2200.
The BalusterFamilyId of BalusterInfo setted.

Actual results
Autodesk.Revit.Exceptions.ArgumentException:“The height height is not valid for the non-continuous rail.
Autodesk.Revit.Exceptions.ArgumentException:“The balusterFamilyId doesn't refer to a valid baluster family.

2200 feet is a very large number. Maybe you need to convert your units? The Revit database length unit is imperial feet.

Thanks for reply，the first question is solved.

What about the second?
I try to set the paramter separated many times.When I tried first,seconed......,sometimes It's OK.but the before times always shows the error.

rt.BalusterPlacement.BalusterPattern.GetBaluster(3).BalusterFamilyId= dalg.GetFamilySymbolIds().First();
