Cannot find Preferences > Keyboard > Shortcuts after enabling dark mode

I am in trouble changing the keypoard shortcut preferences after enabling the dark mode in MATLAB R2023b.

I followed the procedures desribed in Try Dark Mode on Desktop MATLAB with the ‘New Desktop for MATLAB’ beta » The MATLAB Blog - MATLAB & Simulink (mathworks.com) to enable the dark mode. However, after this change, I cannot open the Keyboard Shortcuts Preferences page. According to Customize Keyboard Shortcuts - MATLAB & Simulink (mathworks.com), it can be opened by going to Home tab, clicking Preferences, then selecting MATLAB > Keyboard > Shortcuts, but I only see "Delimeter Matching" preferences and don't see "Shortcuts" preference. Does anyone have a similar issue?
