Section folding unavailable in r2025a?

Hi. I just installed Matlab r2025a and section folding seems to be unavailable. The minus signs that are usually next to the section headers are missing. When I go to the view tab and hit "collapse all," only the comment blocks and loops get collapsed. Any ideas?

Thanks,

On the Home tab, click on the Settings button in the Environment section. Expand the Editor/Debugger item under MATLAB then select Code Folding. Check if the Sections item is selected (I believe it is not selected by default.)
