Matching frames 2011 and 2012 are identical. some error happened along the way.
Figured out that the matching frames for 2011 and 2012 do not have the same number of observations, but the first 10 entries are identical. I think after the matching, both datasets become identical.
@Jo-Schie could you check if there is something special for 2011 and 2012 when you created the matching frames?
