[] Ancient Orca will not swim in aquarium volume block

I didn’t like how the orca looked in an oversized aquarium so I tried using the water volume block. But it seems that it doesn’t move around no matter how big the volume block is. It just floats in the middle of the block as if it is swimming but it won’t go anywhere. Every other fish I put in the block, including my other sea partner (sea turtle) seem to swim around just fine.

I haven’t tried the water volume in any other condos other than the new courtyard villa if that has anything to do with it.
