I created a survey where one of the surveys had a radio-grid question. The columns had values of 0, 1, 2, 3, 4. When I save the question, the "0" doesn't get saved. Having the "0" is preferred because of the way the data will be used later. I haven't tried other question types to see if it is a problem with them as well.

If I go into the database and change one of the values to a "0" it displays properly in the survey so the problem must be in the saving of the question rather than retrieving it from the database. Any idea what I can do to fix this? The version is 2.0.9.
