SDS drop “no free sample slots” error

Does anyone know how to fix the “no free sample slots” error? Obviously, I’ve made sure that I have the slots, even went as far as removing most of the samples from the machine apart from the factory pack.
The sds drop app is communicating with rytm, as the pads react to pressing a pad interface, so it’s not a connection issue.
Sorry for a dedicated post but the sds support is nonexistent unfortunately.
I’m on rytm mki and the os is high sierra
