G'day Chris,
I have managed to duplicate the last 2 flights in my logbook (ICX901 and ICX926). I think it's due to my mouse button playing up and it registering a couple of clicks in quick succession so it cancels immediately after clicking the submit button. I then have to click again to re-send (although in hindsight it appears I don't have to re-send).
I hope it's not too much bother to fix.
Cheers,
Serge
Removed the duplicates for you
Thanks Chris.
