I've just acquired a new Clara BW. If I open My Books, I find a list of authors, none of whose books I own, let alone have loaded onto the device. The attached photo shows a small part of the list under the series tab. If I tap on any of them, I get a screen saying "You have no books yet". If I tap and hold an entry, nothing happens.

How can I get rid of these spurious entries?

If I need to edit a database or something, I'll need detailed instructions, please. My relevant knowledge is negligible.

EDIT: a factory reset doesn't resolve the problem - the fake entries are still there.
