Libra Metadata woes

Hello,

I've scoured the forum and Reddit, but could really benefit from some support.

Here is what I have done:

1. Updated metadata in Calibre (Title, Author, Tags, Cover)

2. Used Polish tool, selected "Update the cover" and "Update metadata" in book files functions

3. Removed ORIGINAL_EPUB versions of books keeping updated EPUB only in Calibre

4. Removed books from Kobo Libra H2O, unplugged device

5. Reconnected device and added books back from Calibre

The covers have not been updated and nothing is changed. For now, I have left the books off of my device.

Could anyone please help me? I would appreciate it very much.
