Directional Specular problem

Hello.

I have this scene and after baking th GI the table in the middle looks like this.
I don’t know why it becomes black, the table should look like this.

Does anyone know what causes this problem? All objects are set to static.

Thank you.

If anyone has the same problem, select the object, go to inspector and check “Generate Lightmap UV2” and then apply the changes.
