This happens because the language settings configured for Protege don't 
match the language settings of the ontology.  The language settings for 
Protege can be set by

   1. clicking View->Custom Rendering
   2. ensuring that "Render by Annotation Property" is set
   3. clicking "Configure"

At the bottom of the resulting panel (which should look like the 
attached diagram) you should see some languages specified.  In my case 
the langauges are specified to be English, US English, Portuguese and 
"no language specified" (the !).  Adding the ! at the end is important 
and might be your problem.  I don't know Portuguese but it is there for 
testing the pizza ontology.

With these settings, if an ontology has an entity with a label which 
specifies the English language then it will render with that label.  If 
the entity has a label that is a French label then it will not be 
shown.  The "!" ensures that entities with labels that are strings or 
plain literals without a specified language will be displayed by label.
