Problems with different floor elevations?

[Lovamist]

I have been trying to build a home with multiple floor elevations on the second floor using home designer 2014.

I have already searched the forum and read the help file for "split levels" and have followed the instructions on how to create multiple elevation homes. I have also followed the order of good building practice.

I am able to create my first plan with different wall heights no problem, but when I create the second storey it overrides my settings for the first storey wall heights and sets all the wall heights the same. In fact it links the room wall heights together - whether or not the default check boxes are clicked.

If I try it the other way and create the second storey first and then try to change the wall elevations below, I am still not able to get my upstairs plan to appear at multiple elevations.

I have retried every way I can think of to get this to work with a simple box structure with a single dividing interior wall on the first floor, but no luck.

What am I missing here?
