When I add a comment on my site -- it post it to Facebook

When I add a comment on my site -- it post it to Facebook just fine --- but the facebook post does not have comment - share links - -so know one can leave a comment -- and thus the additional comments never get written back to my site??? see attachment --
I checked FB and the commenting settings there seem to be correct.

Any ideas??

Also, I have attached another snapshot which has been posted to FB - I think this was a result of someone leaving a star ranking update from a rating plugin --- if you notice the red arrow -- the word false appears?????

Again -- I am not sure where these posting are from -- other than I was testing my GD ranking plugin and these appeared in FB -- so I need to know where the text line that says false comes from

Oh I guess it won't let me upload images
