It's actually supposed to only target kingdoms that have a border with someone of your religion. It's a change we made for RIP.I remember seeing somewhere that each religion has a set of weights placed on kingdoms to decide the target of crusades. The issue with West African is that there are only a handful of nearby kingdoms with a weighting. Once you have conquered all the kingdoms with Crusade weights the game just goes for the biggest Kingdom, which happens to be in India. I had this exact problem with reformed Romuva.
