Which server software? Paper, Spigot...
By the way, on your screenshot, I can't see anything 'cause everything is pitch black. Can you do it again in a clear space and send a new screenshot. Also, turn off your shaders, it may be caused by them.
Ans is there an error in console?

It was caused by Shader.

Too bad! I'm glad you found out. Maybe using Block Display Entities would work, you can try. If they work, I will start working on #19.
