I have a problem with annotations on my Kobo Libra 2.

Initially, I found (I think after a recent firmware update) that annotations weren't working in any of my books - including the ones purchased from Kobo. I could highlight text, and even add a note - but if I clicked on the icon in the margin after adding a note, nothing would happen; and, similarly, if I went to my annotations using the icon at the bottom of the page, it would tell me I had no annotations in the book - even though, when I went back to the page, the text remained highlighted.

I spoke to Kobo support via chat, and they advised me to reset the device, which I did, and reinstalled everything from scratch.

Now I have the same probelm as before, but with a twist: many books will accept highlighting, including (so far) all of the purchased ones. But several of the side-loaded books I've converted to kepubs (using KoboTouchExtended in Calibre) are displaying the behaviour described above. In fact, if I highlight some text in one of these books that has this error, and then use the Annotations plugin to import annotations into Calibre from the device, these "ghost" annotations in fact do show up. But then, when I go back to the device, not only are those particular annotations not listed as annotations when you click on the icon - they've disappeared altogether: no highlighting in the text at all.

So, something weird is going on. I was wondering if it's something to do with the conversion to kepub - but I've tried it several times with one of the problematic books, and it's the same every time.

Any ideas?
