Help! - SD Card shows 2.35 GB used but photo shoot can't be found

I don't know but I am going to assume those first LX7 shots are not recoverable so you might try to duplicate the problem:

Put the card back into your FZ200 (Impatiently waiting to get one myself.) and format the card. Now put the card back into your LX7 and take some test shots. Does the same problem happen again?

If so, what happens to test shots with your LX7 after you format the card in your LX7?
