 ### Fixed
+- control_panel - Fix voltage booking error introduced in the previous fix.
 - control_panel - Fix rounding error in `ManualOutputControl` that caused voltage drifts.
 - octave_tools - Fix bug when setting calibrate to False in ``get_correction_for_each_LO_and_IF()``.
 - unit - ``to_clock_cycles()`` now always returns an integer.
