Can't create "L" configured stair in 2019

[Ferger]

I am working on a renovation to a small 2 story house using stories and levels as appropriately as I know how to. The stair to the 2nd floor was a straight run and worked when viewed in 3D. Client said they wanted and "L" stair, so I changed the parameters to a "L" configuration, which in the dialog box looked like it was working as it displayed 3D, but when I clicked OK and error was displayed and no stair as a result. So I want to another project in 2018 and created a "L" configured stair and it worked. I then converted that project to 2019 and that "L" stair is just line work. What gives?

I tried to make a Steel U-Stair (3 Flights) which was even more complicated.

First hurdle is when switching through the bottom to top height Options

as it may include unwanted Z offsets and such.

Second and bigger Problem was that I had to jump a lot between

different flight Lengths Settings and their Locks vs number of

threads per flight a few Tabs further, accompanied by lots of such warnings

and red empty Stair Bounding Boxes,

until I could force VW to do what I want.

 

(And finally my clients rejected VW's mess with the handrails,

which happens between Flights and Landings.

They didn't like my manual attempts with Railing Tool either 😀 )

The railings at landings are...nutty.
