Strange collision check

So, I dont know why, but collision works wrong. When I scale spawn object in transform, its just don’t spawn.

I wanna make some lvl generation with complicated rooms, but i cant connect any room when use collision check. I dont want to make rooms spawn in other rooms, so it seems collision check is right thing, but its dont work how i thought.

Here some screenshots:

Both Actor totaly the same in ViewPort

Collision box inside

How you can see on collision screen, 2 objects dont collide, but i cant spawn it with “collision handling override (do not spawn)”, when im scale object, so this screenshot has been taken by "collision handling override (default)"

Same shot with mesh rendering

So, any idea how i can fix it? Or how i can create rooms with different size without scaling at least?
