Angel, it's something that often happens when the cutting's axillary buds are already beginning to break dormancy at the time it is taken. I'm afraid it isn't a good sign, but it is easily avoided, fortunately. Just make sure the buds at the nodes of any future cuttings are still dormant. For rapidly repeating roses that generally means taking your cuttings a little earlier, before the plant starts gearing up for the next bloom cycle.
