Reflection probe not reflecting some mesh object in scene

I have a room, and placed one reflection probe in it, the floor have set to proper metallic and smoothness, I can see all scene mesh objects reflected in reflection probe inspector preview, but in runtime, I can only see walls and roof and some mesh objects are missing in floor reflection.

Anybody know how to fix this?

Thanks.

First check on Box Projection option in Reflection Probes.
Then try Realtime mode
Also don’t forget to turn on Realtime Reflection Probes from quality settings

It’s worth checking out Unity - Manual: Types of Reflection Probe depending on your setup (realtime / baked) to check what would be included in the reflection probe.

Thanks for reply.
Here is the screenshot of current scene, but the reflection seems wired, why have gaps in reflection?
