Thanks so much for your help :D ! Turns out there was another validation hidden deep inside the upload library that I use, which limited uploaded images to 1920 x 1080px...!
For some strange reason, though, it didn't limit the image size when I uploaded them, which made it very difficult for me to find the error...
But anyways, it should work now for you, too (just make sure to refresh your window, in case you had it open) !
IT'S FIXED XD !!
