Bizarre issue: Missing only 3 of 400 Facebook friends from Windows 8 People app

Question

Hello! 
I have a bizarre issue with the Windows 8 people app that I'm trying to resolve. 
I have successfully linked my Facebook account (as well as Gmail, Skype, and Twitter accounts) to my Windows 8 people app. 
The app successfully imports 99% (>400) of my Facebook friends, except for **the three Facebook friends with whom I interact the most***. I do see their contacts imported for Gmail and Skype, but there is no Facebook entry for them (so I cannot link their
contact entry to their Facebook account). 
This is a bizarre issue, especially because the app seemingly works perfectly for all but my closest friends. I guarantee I am Facebook friends with these "missing" people. 
Any ideas? I've tried unlinking *all* accounts, then re-linking. No luck. I have tried displaying all contacts, or only Facebook / Skype / Gmail contacts.
I'm running a fresh install of Windows 8 Pro. 
cheers

I noticed that some of my colleagues are missing from the People app, which syncs to our Exchange 2010 server. It didn't take too long to figure out what was going on. In at least two cases, the People app has "merged" the records of two different individuals.
I haven't done any testing to determine the pattern because in my case it might be a perfect storm: In one department, we have two Lauren's and two Mark's. But in the People app, only one Lauren and one Mark appear. But each of those records contain much of
their namesake's information, along with their own. E.g., in the People app, the sole Lauren has two e-mail addresses, two mailing addresses, two home phones, two mobile phones, three work phones (the department line plus each of their personal lines), even
two titles. There is only one photo and one first name and one last name. Mark follows same pattern.
Note that this problem occurs both on the People App running on Windows 8 Pro (on a regular laptop) and on the Surface. (As as aside, this problem does *not* appear on a Windows Phone 7.5.)
To get to the bottom of this issue I did a test. I created a new contact in Outlook with the same first name as a current record, but other than the first name, this new record had no other fields in common with the old record. In the People app, the new
record appeared as expected. As soon as I added gave the new record the same mobile phone number as the old contact, the records merged in the People app. Surprisingly, changing the mobile number on the new contact did not "unmerge" the records. Now the old
contact has two mobile numbers.
While I have the floor, I should point out to any MS employees listening that the search function in the People app really stinks. I have 100 contacts from my company with our acronym in both the Company Name field and the e-mail address, and yet when I
search for that acronym, at best I get a few one-off records with the acronym in the first name field (e.g., our "All Staff" record). I say "at best" because for some reason, at the moment, search doesn't seem to be working at all.
For the record, in general I like the approach Microsoft is taking, and I really want the Surface and Windows 8/Windows RT to succeed. The clean look of the People app is so much better than the pseudo address book on the iPad--but it can be even better.
I'd like to see more display options (at least show the Company name under the contact in the list, and I'd like to be able to sort by First Name, Last Name or Company. And, of course, I want search to work!
That is all.
