Barrier is not visible, Minecraft 1.15.2?

Whenever I build the barrier, I just don't see it, even if I hold the block in my hand I just don't understand. Is it a bug or something or am I doing something wrong?

If you are in the creative and you hold it in your hand then you should see it…

If you have particles out you don't see them.
