Old collection editing layout in swap

I know I can switch between old and new layout in collection editing, in settings.
But why doesn't it affect editing collection from swap page? I would see old interface there too...

This is mainly because when I started my collection here, I misunderstood how exactly I should enter my coins, so I entered like this: "I have 5 F coins, of them I want to swap 4". And now in new interface I see as if I have 9 coins...
