Contao 5.3 / contao-entity-import-bundle 0.252 – Duplicating import source works but throws an error

[pindo-bindo]

Hi,
when duplicating an import source the following error is thrown:
System::importStatic() failed because class "huh.utils.dca" is not a valid class name or does not exist.

The duplicating itself is executed and working. But the error is at least irritating.

Thanks for checking!
