MonoDevelop formatting doesn't seem to work properly,MonoDevelop formatting doesn't seem to work properly

Tried to Google the answer to this, but unfortunately I couldn't find anything. Hopefully someone here might be able to help me out.

I can't seem to be able to reformat code in MonoDevelop to clean it up. I should be able to do this via Edit > Format > Format Document, or by the keyboard shortcut Ctrl + I, but neither is working for me.

See the image below - I added some tabs to line 11, but when I take the steps above nothing happens, and the code does not reformat and remove those extra tabs. I've tried tweaking settings under Tools > Options and then resetting to the default.

Any advice? I appreciate your help in advance. Thank you.
