how is possible CF after 1V1, to give pass to the CB

[July Fourth]

After changing 3formations and all the settings on each one my CF after 1V1 to give pass to CB?
My formations was 4-3-2-1(1AMR,1AML,1CF),4-2-3-1(1AMR,1AML,1AMC)and 4-1-2-2-1(V with DMC) and over 20times(scoring or not)in last 10 games my CF gives pass to CB on 1V1.I got blue arrows on both CB and not,presure on half AND all,Counterattacks and no,man2 man and zone.....
i had the same problem last year with my other1 CF.Cant be something wrong from me and my settings.
PLZ if some1 had the same problem and found a solution give me a reply

Well if your centre half is scoring the goals then does it matter? I have one of my defenders recently recieve a pass from one of my attacking players to score a few of my goals recently, now and again it happens in real life where defenders sometimes get forward to support attacks, Thomas Vermaelen has been getting forward in some attacks when playing for Arsenal.
