edited pics not exporting with lightroom cc

Hey there! im having the hardest time figuring this out. I had just finished editing an album and was going to start exporting the photos out of lightroom. I am not able to do so for some reason now.. some of the photos are previewing with a different preset but when i pull them up individually my edits are visible; however when i go to export the photo it does not export with my edits and its super frustrating. any help would be greatly apprecaited
