Particles on Bedrock servers

I am a volunteer for Lifeboat Network, and not just Lifeboat but all servers have been complaining that some particles are not working in the new update. You can see the particles themselves but their color isn’t showing up on them, they’re just brown. This is majorly affecting Lifeboat and there’s not heaps they can do about it because it’s a Minecraft problem. This needs to be fixed ASAP so that servers don’t have to keep worrying about it. Thanks!
