Order of field in select_multiple question in xls export confusing - is it correct?

My multiple_select field has a choice_filter [not(select…) type].
It has 10 possible responses.

The choice_filter is correct - namely 1,3,5,9 i.e. the 4 of the 12 options not selected.

When I look at the xlsx download the 1 3 5 9 is correct in the first multi-select column.

But when the columns are split up into 12 columns the order is 10 - 1 - 3 - 2 - 5…

I would expect the order to be 1-2-3-4-etc-12

Why is this?

The order is strange but the answers are correct.

Very confusing - can anyone explain?

I have attached the dowloaded xlsx file - look for column qq11 for the first occurance of my query.

Thanking you in advance.
