It's not a malfunction it's the way he positioned his players in their box.

His RB is positioned slightly up moving him to a wingback position in the same zone with the DMC, making the formation 3-2-...

His 2 MC's or AMC's make it 3-2-2...

Finally his AML and AMR are pushed upwards in their box moving them to the striker zone thereby making the formation
3-2-2-3
