Duplicate Labels options disabled for point features

Recently have found that the duplicate labels options, for point features only, are all disabled.
I can make changes in the "Point Settings" section, but all the options under "Duplicate Labels" in the Placement Properties dialog, are all greyed out.
The placement properties are not disabled for line and polygon features.  These all work okay.

I am using ArcMap 10.0.  I am not using MapPlex.

Any idea what is causing this?
