Another question that's likely to have pebkac as it cause: I have just sideloaded a series onto my Clara. Only AFTER doing so did I notice that in 6 of the books, the author's initials are separated by periods, in the rest of the series, they are not. I did a bulk metadata edit so that the whole series shows initials separated by periods, then selected "update cached metadata on the device".After ejecting the device, no change in the "authors" list. What have I done wrong this time?
