Photo order: Portfolio website made using LrC

I am using LrC 12.4.  I am currently creating a photo website using LrC and Portfolio.  I have read many webpages from Adobe and others with info on how to do it and also watched multiple tutorial videos.  I understand the basics and have created part of the website already, but it it not ready to be published.  I am having a problem with regards to the photo order in the website grid view.

In LrC I have a collection of photos for one of the photo albums on the website.  I have them sorted by capture time with the newest on top.  I then synced the collection to the cloud.  After that I went to the Portfolio website, created a new page selecting the Lightroom Album option that pulls the photos from the cloud and puts them in a photo grid page on the website.  The information I read said the photo order on the website would match the photo order in the collection on LrC.  Unfortunately, it appears there is a bug because something weird is happening.  I hope it is just that I have done something wrong though.  The photo order on the website appears to be correct for photo #3 until the end, but photos #1 and #2 are old ones and are not in their proper place.  They are instead put right at the beginning.  I verified that in LrC they are in the proper order.  I also checked the album on lightroom.adobe.com and they are in the correct order there as well.

One more weird thing I noticed.  I read that the album thumbnail on Portfolio is the first photo in the album.  In this case the first photo is an old one the wrong place sitting in the #1 position, but the thumbnail is the proper photo which is the newest photo sitting at the #3 position.

I sure hope someone can help me.  I want to make a website using Portfolio, but this problem is preventing me from publishing anything.
