Preferred Formation

As you go to your own profile, there is a box which shows your preferred formation and tells your playing mentality etc.
I have been wondering why the preferred formation shows me 4-4-1-1 as I have never even used it, mostly 4-3-3 or 4-2-4. I have seen this in previous FMs too.

Anyone knows?

My guess is that it isn't working properly. Mine is showing also a formation I've never used
