MATLAB: Code Sections disappeared. Cannot use %%

code foldingcode sectionseditor

I closed MATLAB and when I re-opened it, all my code sections were gone. I had previously enabled code folding around code sections as well and I can no longer do this.
For example, I have a code which has:
A=10;
B=20;
C=A+B;
D=A*B;
Previously, I could fold up the first section and run it separately from the second section. Now these code sections have disappeared. Any help or info is greatly appreciated.
I also cannot fold up my for, if, while statements etc. I have checked in Preferences and Code Folding is enabled.

It sounds like MATLAB hasn't been able to parse the entire .m file - I had a similar issue until I realised one of my if/for statements hadn't been terminated with an 'end'...maybe until MATLAB is able to parse everything completely it doesn't know how to interpret context-sensitive markers like code folders and section breaks.
