Sort order in myportfolio.com

I am uploading several lightroom CC collections to my myportfolio.com. The images appear in the same order as in lightroom. Some in capture time newest to oldest, some in oldest to newest sequence and some in custom order. However one collection always appears in capture time sequence newest to oldest irrespective of how it is sorted in lightroom. I have tried everything I can think of. This is a trevelog collection which needs to sort oldest to newest.

Does anyone have an idea of how to solve this.
