hemblem5 has started this off perfectly.
Firstly, yes I do live in the UK. A caching issue could potentially be the problem, it'd be interesting to see if that's what fixed the issue.
Just to expand on hemblem5's point, the best way to see exactly how many pages Google has indexed, is by using the search operator **site: **(kudos to hemblem5 for mentioning)
Using this search operator on both the US and UK site, we can see the following results:
site:itelligencegroup.com/uk/ Google is currently indexing 1,160 pages
vs.
site:us.itelligencegroup.com Google is currently indexing 879 pages
We can also see that when using:
site:itelligencegroup.com Google is currently indexing 3,130 pages
From a quick look at the above, I can also see that the domain has 3 sub-domains:
I think going forward, the best thing to do would be to see how many pages you actually have across the site. If there all being indexed then there's no huge issue regarding making changes. If they're not then I recommend following my advice in the previous post.
A good tool to use to find all your pages is Screaming Frog SEO Spider Tool. However I would recommend running the tool outside of peak visiting hours as it can sometimes cause the host server to slow down in response time due to the large number of requests.
If you have any questions just ask.
Let me know how you get on.
