Auto Stairwell problem

[freebird_wr]

Hello,

I have crept upon a problem that I can't figure out. I have a set of stairs on the first floor that were extended to the second floor without a problem. Now, when I select "Auto Stairwell" for those stairs, I get an info pop-up that says "Cannot find the floor above the stairs in which to place the stairwell." Is this something that someone has run into and has a solution? Thanks.
