Request Need some help with the mesh

[DarkKidd783]

I dont know if this is the right place for this, but i tried out the ex nilihlio mod and i purposely made an account for this. I placed a sieve but when i went to place the mesh, it refused, i right clicked, left clicked, dropped it, tried crafting with the sieve and its refusing to put the the mesh into the sieve. idk if i messed something up or what.
