Unable to debug local variables in VS2013

When stepping through the code from a breakpoint, I noticed that not all local variables don’t show up in the local/auto inspector. Is there a setting to enable them to be displayed or is this not possible?

I can’t figure out how to mark this is a dupe, so check that one out.
