Form template fires twice when submitted using enter key

[JordanMarr]

Did you use e.preventDefault()?

<form @submit={Ev (fun e -> e.preventDefault(); save())}>

</form>

Yes

[JordanMarr]

And you are using a <input type="submit"> button?

Correct, I also tried what others said e.stopImmediatePropagation();
