RTX beta No reflection of player in mirrors (red nether brick)

I was testing the color light and shadow map on Minecraft RTX (on an RTX 2060) when I noticed something quite strange when placing mirror blocks (red nether bricks). Only the block I was holding and the surroundings would reflect. I tested turning DLSS off and back on again but nothing happened. However, when I switched to third person, Steve would magically appear in the mirror again. Is there a way to fix it because it is quite disconcerting when entering the mirror room in the map.

Thanks a lot! Hope you can help.
