stair and wall/slab cross-section

[Bara3]

Hello, I have tried to have clear connection between a wall and a stair, I used the same material but it is not working. Can you please help me what am I doing wrong?

Isn't there a finish on the wall?
Then you have to use SEO.

There is not, it is just a plain wall. 

I thought that a finish might be a problem, but it would be great to connect it also when there a finish on the wall.

It seems that the wall and the stairs are not connected correctly.

If there is a deadline, you have to do SEO.

If the material is different, it will not connect.

If you match the material

And when asking a question, you need to provide basic information.
If it is the connection between the stairs and the wall like this time, it seems that it will be easier to answer the information about the wall and the stairs if you tell them with pictures as much as possible.
