Same here. I did some testing and problem seems to occur in MCC. (I use V 1.6.1.14 on Mac).
Banks and presets are not automatically refreshed.
If you create / save a new preset on MB, it does not show in MCC.
If you disconnect the MB (unplug USB) and re-connect, the new preset shows up in Matrix View, but not yet in List View (...).
However, you can select the 'empty' preset and rename it. MB updates automatically (reselect the preset to check).
In MCC you have to re-select the bank in order to refresh the preset list of that bank. Now you see the new preset name both in MCC and MB.
Hope this can be easier in future release of MCC.
