wait, what is confusing here? The pics are pretty clear what the issue is.

I have a chain that is clearly 1/2" x1/8", evidenced by box and the fact that it fits another chainring that is labeled as 1/8" width.

The chainring in question, is supposedly 1/2" x 1/8", but the confirmed 1/2"x 1/8" chain does not fit it. Does anyone else own this chainring? Can anyone tell me what is going on with it?

I am not trying to confuse anyone, as I am thoroughly confused by this matter. Supposedly all chains/chainrings have 1/2" pitch, okay. So why doesn't my chain fit? This Sugino chainring is making me sad.
