Bottom part of stair goes below floor

I have created a stair (AC19), but since the bottom part goes below the first step (instead of being flat), it is visible below the floor in elevation/section. How do I change this? I assume there's a setting somewhere, but I haven't found it. See screenshots below.

There should be a setting within the stair to change the option to start the rise at floor level or the treat at floor level. You can also change the thickness of the bottom rise to match the depth of the floor slab.

Look at Stair Settings > Stair > Structure > Flight Monolithic > Support Connections to see the options for changing the bottom and top of the stair.

In your case, you probably want to ZERO the Lower Slab Thickness

By the looks of it, you will also want to change your Top Tread Level  to Below Floor Level so that you can get your structure to finish to the bottom of your slab.

Thank you for the help everyone! I managed to solve it by updating the structure settings as suggested by David.
