Extrapolated boot sector and current boot sector are different

Why is “Extrapolated boot sector and current boot sector are different”?
I am currently trialling Program Testdisk 7.2 – WIP on healthy hard drives and I am very impressed and eager to learn.
The drive I am trialling Testdisk on is a healthy working Hard Drive. 80GB. The complete drive is partitioned as one 80GB Non-Bootable Primary partition and formatted as NTFS, to be used as a data drive.
When I navigate to Advanced -> Boot, the Boot Sector & backup are OK
Under repair MFT & MFT Mirror match perfectly
But under Rebuild BS “Extrapolated boot sector and current boot sector are different.”
Because the hard drive is non-bootable, I expect the BS and backup to only contain the MFT which is identical. Why is the BS different?
Thank you in advance
