@mockaroo - response on sequential issues?

I am using a dataset of specific dates and need those in a primitive array. i believe I should be able to do this by specifing the field name with [100] for the number of dates I want - from a dataset - with sequential selected. The sequential function does not seem to work as intended.

This is what I get - even though my dataset has dates sequentially - skipping some for holiday’s - others for vacation days.

[{
“dates”: [
20160101,
20160101,
20160101,
20160101,
20160101,

However, if I select ‘random’ - then I do get days - but not ordered the way I need them:
{
“dates”: [
20180729,
20170314,
20170420,
20171126,
20200129,
20180809,
20190707,
20180208,
20170110,

With Sequential I would expect the order in my dataset.

I also attempted using character sequence - but sequential also there does not work as expected.

It seems the way sequential is described @mockaroo - I should be getting the data i need - but it seems to be broken? Is that the case? Will it be fixed? Do I misunderstand how it should work?
