Hi Matadem, it means that there are 2 or more curve control points stacked up on the same location.

That kind of messes up some of the mathematical properties of the curve so it's usually good to get rid of those.

This mean you have more points overlapping than you should ... with 2 curves like in you example, you probably have 3 points (or more) instead of 2. Try to drag out one of those to fix it.
