Is it possible these legs are actually connected but contain some moisture. As water has roughly the same refraction index of glass it is sometimes difficult to see properly. This would also explain why the leg looks like it is partially filling. Most unconnected legs reasonably close to a damage should break into the centre with just a light tap in the correct area. Are you also using a UV shield as premature curing can be a major problem in some places in fact I would say most. Please do not take this reply as a slight on your expertise, I am just trying to come up with a few suggestions.
