Why does my Descending Bubble Sort not work for an input in ascending order?

Question

This code works for most inputs except for when the input is in ascending order.

e.g. input is [1,2,3,4,5], output is [5,1,4,2,3], expected is [5,4,3,2,1]

DescBubbleSort(A) 
    for i from n downto 1 do
        for j from n downto i + 1 do
            if A[j] > A[j − 1] then
                A[j] swap A[j-1]
    return A
