I wanted to try something out, so after adding the missing books back, I connected my Libra to my PC and opened Calibre. Every time I connect to Calibre, I have it set to update the page read count. After it did this, I ejected. The result was the same as the last time, all the books but 6 have disappeared from the collection - the same six. They're all books I've downloaded from my Kobo account directly on to my Libra, the others were sideloaded.
The collection persisted through multiple connections to Calibre 4.23 under the previous firmware, so I'm assuming that something about collection management on the device must have changed with the most recent firmware.
