[Q] I think I have two recoveries running parallel topic

So I had originally had TWRP/Hyperdrive on my phone, and switched to CWM/Cyanogenmod. I noticed now that I seem to have two different recoveries on my phone, because if I hold up+home+power I can go to a different version of CWM Recovery than if I use the Rom Manager app to boot into recovery. How would I rectify this? Would it involve wiping the /boot partition? I don't know where/how recoveries are stored so I don't understand how I can have two.

Doing a fresh install of a ROM has not resolved this by the way. And actually currently, I can't hold the buttons and boot into recovery at all, it gets stuck on the Samsung logo. I can only get into recovery via Rom Manager or Reboot options if I'm in android.
