For instance, if you have Dagger’s cure staff or whatever equipped she will only cure the enemy… try changing your equipment… if that doesn’t work you may have to start over or just not attack with them.
I would try changing their weapons cuz i have had trouble with that too.
go to the menu then to ability where you can equip blue stones in to abilities and dejunction the healer ability because that makes your characters heal when they attack.
unfortunately if i remeber rightly when u use cheats it gives you every ability and automatically equips every ability possible and it is impossible to take them off which is bad because it means your stuck eith the healer ability for the rest of the game unless you decide to start again and actually complete the game without the use of cheats
