steel construction - member design problem

[Iva3]

Hello,

I have  a steel construction with masonry and concrete walls. All steel members are good (<1,0) when i designe them, except members 205, 207, 208 (profile 100x150x5). I tried to replace them (and others that where 100x150x5) with 100x180x5, but I have same problem. I can't find problem in modeling, so I'm asking you can you help me and take a look at model.

Thank you in advance,

Iva

@Simau The walls below steel structure were connected to steel structure. Here is the picture of corrected model

Now I have some distance between steel structure and concrete walls.
