Hyper-V Export failed for virtual machine

On some machines, when exporting, I am getting the following error:

Export failed for virtual machine ‘machine’ (xxx-xxx-xxx) with error ‘The requested operation could not be completed due to a virtual disk system limitation. On NTFS, virtual hard disk files must be uncompressed and unencrypted. On ReFS, virtual hard disk files must not have the integrity bit set.’ (0xC03A001A).

Host is both Windows Server 2016 as well as 2012R2, and the filesystem is never compressed, also it is not ReFS, so it is uncompressed, unencrypted NTFS.

I don't know if compression is somehow enabled for the virtual disks, I was not aware of enabling that.

The export target is a network path, the underlying folder is compressed, but that should not matter?!

Some other VMs on the same hosts export fine to the same location.

How can I export the VMs?
