Rain neither rendering nor working at around y lvl 18

I’m currently working on a build that goes deep in the ground and the rain just stops for like 15 blocks which is really annoying since I use my trident a lot. Here is the clip showing how the rain just disappears, and no, it did not clear up it was still raining. https://medal.tv/games/screen-capture/clips/moeegnhBTcHT0I6kV?invite=cr-MSxqOTksMTkxMTA4NTMx
