Nothing untoward.
This table you mentioned seems a bit suspicious to me.
As I've said the engine fuel system is designed to accept fuel (with 260ppm of water present) at the LP inlet down to -45°C (fuel temp) without issue (and they do). What is now evident is that this is possibly not the worst case scenario due to the type and formation of ice present.
This kind of system icing testing has in the past prompted modifications to FMU Flow Washed Filters where sevo flows are traditionally tapped off. Obviously if a flow washed filter becomes clogged (it shouldn't because as it's name applies the filter is constantly "flow washed") then you can lose control of the engine as VSVA contol et al are servo flow controlled / powered.
