Wrong symbol Plugin water?

I’m looking at the water plugin (which for what it’s good for, it’s better to create a couple of volumes… and reproduce the same effect)

I always get the “error” or “crossed out” icon when I go to put the water

but I can drop it even though that icon appears.


Is it really a bug?

Version: 5.1

Did you ever figure this out??? I’m running into the same issue and the plugin isn’t working correctly for my landscape
