What kind of compression does Calibre use here?
That is NOT a bug. That is a USER ERROR.

What is happening is that the setting to update the metadata is set. So when the eBook is loaded again in the editor, it again modifies the metadata. The original cover is restored because it's part of the metadata that gets updates.

The solution is to turn off automatic metadata updating in the editor. This option is totally not needed because it is USER ERROR!
