Soapy/sweet taste is usually attributed to not enough steep time. We would recommend giving your flavors more time to steep, anywhere between 2-4 weeks, minimum. If you are unfamiliar with the steeping process, you can check out our guide here!:
If steeping doesn't help the issue, then there may have been a mixing error on our part! You can contact Customer Service via e-mail at email@example.com, through our live chat feature, or by phone at (877) 565-8273, and we would be more than happy to assist you further in getting those soapy/perfumey e-liquids replaced.
