(ZCM 11.4.2 on ZENworks appliance, single server)

I am running the ZENworks Diagnostic Center 11.4.2 on my 11.4.2 system in preparation for the upgrade to 11.4.3. The only section I have problems with is the systemfiles check. I am using ENGL's Imaging toolkit. I see a lot of inconsistency errors on files in the package novell-zenworks-zmgpxeclientfiles-11.4.2-11227 in the /srv/tftp/efi/x86_64 directory. Some examples:

File '/srv/tftp/pxemenu.example' is inconsistent!!!
Size: expected = 2930, actual = 2930
Checksum: expected = 16d5cfa6, actual = 16d5cfa6
NoSpaceChecksum: expected = 0, actual = 0

File '/srv/tftp/efi/x86_64/winpe.conf' is inconsistent!!!

Checksum: expected = 462f5efa, actual = 462f5efa
NoSpaceChecksum: expected = c3d35bf4, actual = c3d35bf4

Package name: expected = novell-zenworks-zmgpxeclientfiles-11.4.2-11227, actual = novell-zenworks-zmgpxeclientfiles-11.4.2-11227

Can I safely ignore these errors or is this something I have to fix before doing the upgrade (and if so, how)?

Thanks,
