Fairy Sim bathing like a mermaid

I don’t know why this is happening, and my SIM was never a mermaid in the first place. I made her as a fairy, but whenever my SIM goes to take a bath, for some reason, her legs stick out of the tub like she would be a mermaid. And the weird thing is that I have another SIM who is also a fairy in the house and whenever he takes a bath, it doesn’t make his legs look like that
