From what I can see you're playing with 3 strikers, not one striker and two wingers, right?
Maybe because you're set to wide play your midfielders look to get it out wide but fail to reacht your wide-men because they're not dropping deep enough. Maybe try switching them to be wingers with the Inside Forward setup. They'll still cut inside and get a fair amount of goals but they'll also help with build-up play more, and also help out with supporting your fullbacks, who look vulnerable as it is.
Other than that, how familliar is your team with the tactic? If they're no very used to it, it could take a while for them to tick.
Finally the pressing might be causing your players to drift out of position, so when they do win the ball they'll have no-one to lay it off to. Not too sure about this, but it might be a factor.
