Cache:example.com returns a different site of ours

[iInventedtheinternet]

Doing a google search for our site cache

(cache:our-site-example.com.br)

returns the cache of our feeder domain ( our-site-example.com ) which feeds all our country specific domains.

All the other cache searches for our other domains seem fine.

Any clues as to why this is happening?

What kind of technology are you using to "feed" the content?

[iInventedtheinternet]

Maybe I misspoke. We don't actually "feed content". We just have a .com homepage with a list of 20 links pointing to the 20 countries which we have country TLDs for.

The .com has a PR5. Doesn't get too much traffic. All the traffic is normally on the individual TLDs

The .com page is now in the cache of one of those county TLD's cache using the google operator cache:

It's like Google is confusing the two sites, oddly I'm not sure why this is only happening with only one of those 20 TLDs.
