Can't Mount Replacement Hdd to Same Spot?

I replaced my media hdd with a larger size and now I cant mount it to the same location as the old one /mnt/ultron

I have deleted the ultron directory and recreated it, I have tried using the disks application, I even tried modifying /etc/fstab to have the new hdd's uuid. It appears to unmount instantly when I try mounting it.

I have successfully mounted it to other spots such as /mnt/ultrons just to test, but it will not mount to /mnt/ultron

My current /etc/fstab was created with disks and I have verified the uuid is correct. It even works if I change the mount point to anything else.

Here is my fstab

# /boot/efi was on /dev/sda1 during installation UUID=F1D3-05E0 
/boot/efi vfat umask=0077 0 1
/swapfile none swap sw 0 0
/dev/disk/by-uuid/a815ea68-9d8c-41fa-9534-cabb080013c0 /mnt/ultron auto nosuid,nodev,nofail,x-gvfs-show 0 0
