Group error?

Can someone explain what happened and if they’ll fix it?

it depends on how you interpret "move up to the next valid group" but there is a world where FUT should move to B instead of A, where EDG should then be pushed to D

but its a subjective interpretation so nothing will happen

Even if it moved the way they claim to be there is still no error
They move up the groups until a valid spot/swap, when FUT was drawn into Group C the only valid swap was Group A, because EDG couldnt have been swapped into Group C with Tyloo in Group C and KC was in Group D. So in any interpretation FUT would have been swapped with PRX
