Launchpad error while copying package -- already published

I'm trying to copy my Launchpad package to the new Noble repo,

• I first tried to copy binary package but failed with:

Target series: Noblemy-pkg 1.1.0-1 in jammy (binaries conflicting with the existing ones)

• I then tried to copy source package but still failed:

Target series: Noblemy-pkg 1.1.0-1 in focal (same version already has published binaries in the destination archive)

This is wrong, as the first copy failed, and I don't see it when I tried to "Delete package" myself.

I think this is more or less a launchpad internal error, butis there anything I can do about it please?
