When changing the VoiceOver voice using the speech rotor, voice names are not spoken by their respective voices

When changing the VoiceOver voice using the speech rotor, voice names are spoken by the voice already in use, as opposed to the selected voice. For example, with Alex set as the default voice, when pressing VO-Command-Shift Down-Arrow in the voice menu, names like Daniel and Fiona are spoken by Alex. Previously, voice names would be spoken by their respective voices as you navigated the menu.
