I edited a wedding in Lightroom for the first time. I reordered the images using custom order, then renamed them all and exported the files, but the order keeps changing. I uploaded the files to Zenfolio and selected file name order, but the order kept jumping and also in Lightroom when I view the order, the photos are not in the order I renamed them in and sometimes when I click on a photo, it disappears altogether. Please can someone advise me on how to get these 700 images ordered as I want then, renamed and exported to stay in that order. Thank you.
