1-11 squad number problem

When I play a 4-4-2, my strikers used to be #9 and #10 now, no matter what I do, they go back to the way it was before FM 12 in that the numbers for the players go

2-4-5-3

6-8-9-7

10-11

How do I sort it? It's incredibly furstrating when I set up my tactics for it all to reset when I go into a match yet when I holiday, it works fine.

I have the same problem !!
