The Open Graph tag specified on that page looks like:
<meta property="og:type" content="danhgia:memory"/>
Do you know why it would be set to 'memory'? Is that another object type you've created? Should that be associated with different listings and not that one?
Anything you can let us know would help. That type doesn't seem to match up with PC Game or Tablet, so I'm a little confused as to where it's coming from.
Thanks,
Alex
