Time Machine Disk 'name' change

So I have a 3tb external hard drive originally named 'ABC'. Soon the name was changed to 'XYZ' and was using it as Time Machine Backup.

Recently, I got an Airport Extreme router (last gen) and was hoping to use it as the Time Machine drive too.

Now, when I go to Time Machine setup, it shows the drive name as 'ABC' (which was originally called) and a new external called 'XYZ'. If I select XYZ as backup disk, it would start a fresh.

Is there anyway to make sure it just uses the initial data from when I sued to backup with USB cable.

To summarise:
1- Initial time machine hard disk ABC renamed to XYZ
2- Setting up Time Machine over Air Disk.
3- Time machine finds XYZ but identifies as a new drive.

Anyway for air disk or time machine to use the existing drive?

Ok so I did some digging.

After plugging in the disk on my computer, it gave a notice that Disk Name has changed or similar. After pressing okay, it began to make the complete backup again.

When I entered Time Machine, I saw current and previous data.

Putting the disk to Air Disk, it recognized the disk and made a differential backup (for some reason it was 1.5gb but okay).

Now, when I enter Time Machine via any method, I can only see todays data.

There are 2 things in Network:
1) The drive name and backups (Backups.backupdb stops at yesterday)
2) A new disk called Time Machine Backup which has todays data.

Is a workaround even possible or should I stick with just USB backups.
