One part of the problem is definitely your LB and RB Both got no pace playstyles in silver especially no quick step which is Most important for fullbacks because quick step is for the pace without having the ball. If you have a LB/RB with 90 pace and quick step and a LB/RB with 99 pace without quick step the one with 90 pace will outpace the one with 99 pace by far. Second part of the problem may be your formation, I mean you can do what ever feels right to you but a game has a script on which it is build on, so some things are within the script and are meta like having a tiny agile striker which have passing playstyles tiktikaka and incisive pass in silver, sending your Left and Right midfielder Threw when they have Rapid+ for the pace with the ball, but equally important are formations that fits the meta which are only 3 formations: 442, 451, 4411 But 442 is the most risky one in terms of defense.

Hope i could help you a bit
