is this saw blade faulty?

This may be the stupidest DIY question ever, but I want to make sure before I return it: is this non-ferrous metals saw blade faulty ? In the picture, see where one of the titanium carbide teeth seems to be too large and to extend into the expansion slot. BTW, I had made 4 cuts of 9-15" or so, in 3/16 aluminum plate, before I noticed this; it cut ok, seems like it could have been smoother, but I've never cut aluminum with a power saw before, so I don't really know what to expect.

Here is the blade:

... and the picture of mine:

Yes, that is a defect. If you really need to use the blade now, you can chip or grind off that extra slag - it's just one tooth out of 80. If you have time to return it, it is a legitimate manufacturing defect.

As an aside, I note that blade has a negative hook angle, which is what you want on something like a radial arm saw. If you know what that is and bought it on purpose, that's great, but to learn more about the various aspects of a saw blade, check out this article at Rockler. Some people stop looking at the tooth count, but there are other important variables.
