Strange artifact in reflection capture

Hello, everyone.
This is my first post on the AnswerHub. Hopefully someone will be able to help me

I have this bathroom scene with a mirror covering the whole width of a wall. I set it up with a metallic reflective material and a reflection capture. The quality/resolution of the reflection is not great, but that is not the main issue…

The real problem is that the ‘captured’ scene in the mirror appears with huge artifact covering a big part of the reflected image. It effectively ‘blocks’ the view of most of the opposite end of the bathroom. Please check the image below; it is the big grey mass you can see close to the centre:

I tried to use a sphere capture actor instead of a box, I tried to move its position, change its scale, fiddle with some of its capture parameters… to no avail.
Funny thing is that the artifact appears somehow to have a specific geometry… When you move the capture actor, you can see the scene changing in perspective, etc., but the artifact seems to keep its form. Almost as if there was a ‘ghost’ mesh in the scene that only the capture actors could see!..

Below you can see the rest of the bathroom through the eyes of the player.

Has anyone got any ideas regarding this situation?

Thanks in advance for your help!
