When I re-set an Adobe Portfolio page from a Lightroom album, the photos sequence is not maintained

Hi! I've built a fairly extensive travel photography website using Adobe Portfolio linked to collections I've built in Lightroom. In general it works really well, but one small problem is when I decide to add or change some photos - if I use the 'Re-set from Lightroom' in Adobe Portfolio, the photo sequence doesn't match the Lightroom collection. I have to then use 'Manage Images' in the photo grid of Adobe Portfolio to manually get them back to the right sequence, but that's a bit annoying. Even if I delete the web page, update the website and then re-create the page from the Lightroom album, the same problem remains. Any ideas?
