Nope, and my magic level is 99.
I relogged but it still doesn't indicate.

Can you check if it works if you take out some water runes?

I think it's an issue with the water staves. If you wear a water staff and you have no water runes in your inventory, it will not show any water spells that you could cast (it still works though)

I tried it and with the water runes, it show's you can use it.
