You're still wrong.
We have been playing 3-5-2. The numbers 5, 4 and 6 are Chester, Bruce and Davies, our three centre-backs. 27 and 11 are Elmohamady and Brady, our wing-backs.
Clearly, what's confusing you is the fact that Elmo is very far forward whilst Brady is much deeper, one assumes? This is simply because Liverpool's right-winger, Raheem Sterling, is a very dangerous player. As such, Brady was largely man-marking him at Anfield (and did a good job in doing so) and couldn't get forward as often as he'd like due to the threat posed by Sterling. Whereas, on our right Elmo was encouraged to venture forward as much as possible. A further consequence of this, is Chester (5) drifting out towards the full-back position to cover Elmo, hence why you must have assumed he was playing right-back, which he wasn't.
I hope this helps, but I can assure you we play 3-5-2 (you could argue 3-5-1-1 whilst Jela is out injured), regardless of what you may interpret from a heat map.
Erm...you do realise that all you said above simply means that you set out to field 3-5-1-1 but then adapted to Liverpool's tactics and ended up fielding 4-4-1-1. The fact that there were 3 players who a predominantly centre backs on the pitch does not necessarily mean that 3-5-2 / 3-5-1-1 is being played - as the average position map shows
The other option is that you are playing 3-5-2 and therefore your players are not fulfilling instructions. But I think they deserve more credit than that
