tahts because you installed OUDHs recovery, not clockworkmod
. oudhs is a spin off of cwm and has some unique features that i put in. i use nandroid manager with it. however even though i have my own recovery i still use twrp and goo manager on my devices (twrp is pretty awesome :P).
since you are rooted getting either cwm or twrp is a breeze, use either goo manager or rom manager to flash the respective recovery.
