I have looked at this one and it is with development - the issue is caused
by what the Developers call contnuations on the alignment - if you use eg
Explore Object on an alignment, and in the case of the Cul De Sac in
question, if you go to the Right Hand Side of the alignment prior to the
cul desac you will see if you move the cursor away from the alignment that
it snaps to a Phantom alignment - that is the continuation of the alignment
(not sure why it is there or what it is really for, however the 3D
Reference lines that you are drawing on the profile clash with that
continuation alignment creating the issue that you are seeing.
Development are looking at how that can be resolved in these double back
alignments that you have on this project.
