How do I make the input type radio so that it can be checked?

I have the problem that when I insert the check to the first one and then I insert another one and the check is passed to the new one that is entered and the idea is that it stays there in the first one that I entered.

method

private async Task GuardarModalDireccion(){    if (isEditDireccion)    {        dataDireccionGrid[dataDireccionForm.INDEX] = dataDireccionForm;    }    else    {        var splitDireccion = dataDireccionForm.CIUDANEID.Split("-");        if (splitDireccion.Length >= 3)        {            Direcciones direcciones = new Direcciones            {                CIUDANEID = splitDireccion[0].Trim(),                DIRECCION = $"{dataDireccionForm.DIRECCION}, {splitDireccion[1].Trim()}, {splitDireccion[2].Trim()}"            };            if(dataDireccionGrid.Count > 0){                direcciones.ESTADO = 0;            }            dataDireccionGrid.Add(direcciones);        }    }    await modalDireccion.HideAsync();    dataDireccionForm = new Direcciones();    StateHasChanged();}
