Well, then it looks as if it is completely a bug. You shouldn't even have several versions of Bless or Cure Wound at level 1, so it's behaving wrongly at several levels.
Hmm, aren't they the 'always prepared' spells given by the life domain? That's one version, and then the 'usual cleric' version is the second version?
I could easily be wrong, but I thiiiiink that's the reason isn't it?
