I’m not seeing this issue on my site, but mine is the latest ver 3.1 beta, so is different from yours. I’m not able to check my standard ver 3.0 test site just now, so can you try a similar edit on your Royals site? If it’s an issue there I can login and take a closer look for myself.
Can you also check the kiwitrees error log to see if that holds any relevant info?
