Default [Q] KitKat could not see JB nandroid

My Jelly Bean phone is rooted with Safestrap 3.71. I was using the stock ROM and decided to try a KK ROM. I did a JB nandroid so I could revert back if KK didn't work out. It didn't. Calengoo, my critical calendar app, kept FC'ing. I couldn't fix it. So I went into Safestrap 3.72 recovery, wanting to restore my JB nandroid. But guess what? KK recovery did not see the JB nandroid ! Is that normal? Is it because of the external SD card problem with KK?
