MPK249 controls not mapping to Cubase

I have an Akai MPK249 MIDI controller and Cubase Pro 10.5. The MPK has a Cubase map already installed. However, the transport controls & rotary dials on the MPK do nothing in Cubase. I recently started using Akai’s MPC Beats software and realised all the MPK’s rotary dials assist in MIDI editing (panning, zooming, quantizing etc etc), and the transport controls work in this software. How do I get these controls on the MPK to work in Cubase?
