Problem with Contains - missing records

Hi, 

I have created a full-text catalog for my table tDoc, but when I search records with contains, 
I dont get all records. I search for 16949, and with LIKE, I get all 5, but with CONTAINS I only 
get three. Se image below.

What I am doing wrong?

Clik here to view.

It does not make any difference if I use wildcards (*) with contains.
