I didn't think it was a Calibre change between 4.18 and 4.19, just listed the version numbers for completeness.

I suspect they have changed something, as up until very recently the dual image upload work flawlessly.

Could also be something to do with the specific book. It is one I bought from Amazon and imported into Calibre, then sideloaded. I removed the ISBN and mobi-asin tags before sideload -- not sure if that is necessary.
