Why do I get reflections from capture and not from planar reflection?

Hi all,
I’ve been searching around here but can’t really find a similar issue. I am trying to reproduce a nice reflection on a pool water plane where I have a water material applied. To do so, I am using a planar reflection but I am not getting the desired result.

When on Editor view, I can see the reflection image of the planar reflection (which is showing exactly what I would like to see reflecting on my WaterMaterial)

But when I go to Game view mode, the reflection image is not what I was seeing on my planar reflection.
Also I’ve noticed that If don’t throw any reflection capture volume (other than my planar reflection) I am no getting any kind of reflection. Here I ve turned the opacity to 1 on the water material, so I shoud have a mirror-like effect, but as you could see, it’s all black.

When I throw a Reflection volume(box or sphere) i get the reflection from this volume instead of the one from the planar.

I’ve enabled Clip Plane option on the project settings and restarted the Editor.

What am I doing wrong? How can I get on my water plane the reflection that I see on the planar reflection preview, instead of getting the reflection of the capture done with the Box reflection?

Any help someone? Thks
