camera roll completely out of order

i just switched all my files from my old phone to my new phone. i got onto discord to chat a little with some friends, but when i opened my camera roll to look at my images they werent in the right order. i went and checked both image file apps on my phone and the order of the images in both apps was the same as on my old phone, so this is just an issue with discord. i downloaded a new image and it was at the top of the camera roll like normal, so why is everything else out of order and how do i fix it?
