This doesn't seem to be a problem, but is a little unusual.
I edited one of my existing tables and inserted into the column list on the top left was a column with no name definition. That empty definition was not repeated in the textual definition below.
Looks like spurious data to me! I have a screenshot if it would be helpful to describe.
