I've tried this with both instrument racks and effect racks with the same results.
1) create the device
2) hot swap the device using the mouse (not Push)
3) the parameter names (macro labels) for the device do not update on the Push display.
You can force it to update by going from device mode to another mode and then back to device mode
Hot swapping from Push itself works correctly.
Ironically, hot swapping with the mouse does not update the Push display, but it does update my Novation Impulse display correctly with parameter names.
Bug - Hot swapping with mouse does not update Push Display
