Letter 'A' not showing up as a property value

Strange one - I have a drawing property (for revisions) that is to use just letters, and when one has the value of just 'A', it doesn't show up.  Every other letter works, and 'A+SPACE' will work, but not just 'A'.  Is there a coding reason for this?  I assumed the value when labeled as text would be just that and not be evaluated as anything...
