However, on disk, we have very different file size & checksums:

If we generate Packages differently with:
apt-ftparchive packages . > Packages
Generated Packages contains this time correct file size & checksums:

What is very strange is that all other packages in the same folder are
correctly described by Packages when using the first method for
generating Packages.

I have the same issue with another package in another folder.

I have also uploaded the deb.
Any suggestion?

N.B: I can upload the second package if necessary.
