A change in handling of required attributes with defaults

We have an attribute that is set to "Editable and Required" for TDNext.  We also have a default dropdown selection set with the default enabled option selected.  When filling out the form in TDNext we see the default show up in the form but the application will not allow us to save the ticket and returns a RED error box at the top of the window stating that that attribute is required.  This error is even different then how other required attributes are handled when they are not filled out at submission.  Those attributes are handled by the window dropping down to that attribute with red lettering under it saying it is required.  Has something changed with required attributes that have a default preselected?
