Cant see the image in my mobile but had the same problem with a front sprocket from snell. Couldnt find a 13T sprocket att my local dealer wich made me go with snell.
For me it went to far in making the chain alignment bad.
My solution was to machine down the old worn out sprocket and only keep the back ring as a separate distance for the new sprocket.
(A flat distance ring should work aswell)
Is this what you are refering to or is the sprocket to thin for the chain aswell?
