Lightroom Slideshow Problem

[smoke665]

It's been a long time since I've built a sideshow in LR, and I've run into a problem. I built a "collection" of images from several different file folders, by dragging and dropping. Once the "collection" was complete I reordered the images by dragging and dropping. So far all is good, when I click on play the slides display in proper order. The problem occurs when I click on create save a slideshow. The newly created saved file has all the images but the order is all messed up. Anyone have any ideas on what I'm doing wrong??
