Cannot replace drive in zfs pool - "Replacement device too small"

I have an existing zfs pool that was created in unraid. One of the disks in a vdev was showing errors so I removed the failing drive and installed a new drive, however when I try and start the array after replacing the drive I get a pop-up saying "cannot start array - replacement device too small"

I have used fdisk to confirm the replacement disk is the same size as one of the existing disks in the vdev so I am not sure why this is happening.

/dev/sde is an existing drive
```root@Unraid:~# fdisk -l /dev/sde
Disk /dev/sde: 12.64 TiB, 13902809137152 bytes, 3394240512 sectors
Disk model: ST14000NM0288 E
Units: sectors of 1 * 4096 = 4096 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 16773120 bytes
Disklabel type: gpt
Disk identifier: 3C5DFD51-A0B0-474D-BC82-D897A4391E43

Device     Start        End    Sectors  Size Type
/dev/sde1      8 3394240506 3394240499 12.6T Linux filesystem```

/dev/sdd is the replacement drive
```root@Unraid:~# fdisk -l /dev/sdd
Disk /dev/sdd: 12.64 TiB, 13902809137152 bytes, 3394240512 sectors
Disk model: ST14000NM004G E
Units: sectors of 1 * 4096 = 4096 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 16773120 bytes
Disklabel type: gpt
Disk identifier: 5D604A8C-60EE-4D84-9F15-5653AF83DDA4

Device     Start        End    Sectors  Size Type
/dev/sdd1      8 3394240506 3394240499 12.6T Linux filesystem```

Any help would be greatly appreciated!
