Boox Note Air 4C Metadata

I have just bought this machine, mainly for reading ebooks with a larger screen (eyesights getting worse). I like it very much. I sideload my books with Calibre but cannot find any metadata on the Boox anywhere.

On my Kobo Libra Colour it was very easy to see. Am I being very thick and not realising that no metadata is transferred from Calibre to Boox? Probably.

However, if anyone can help me resolve this issue, or tell me what to do (apart from sending the machine back for a refund) I would be very grateful.

Thanks
