Reflection problem

I have problem with lighting in scene.

Scene have 31 lights, set on Mixed.

I increased pixel light count to 50.

Some of lights dont have reflection in scene.

On screen are two rooms on the right is correct lighting and on the left is lighting without reflection. Settings are same in both rooms.

Here are lighting settings :

Any ideas what is wrong ?

Thank you for answers.

The problem is not the light, is the material of floor. Try to change values of the material of the left floor, move sidebars of metallic and smoothness, and check the boxes on down of material ( Specular HighLights and Reflections )
