Entity null option only displaying a 'N' instead of NULL or NOT NULL

I'm using ER/Studio 17.1 and have reverse engineered a few DBs.  Just about everything seems to be working as expected, however the entities are only showing a single letter for the NULL/NOT NULL info.  IDENTITY is the same, it's only showing an 'I'.  Expanding the Entity does nothing.  Am I doing something wrong?  Is there a hidden option somewhere that will display the full text?
