Squad builder changing sbc formation

I was doing sbcs and used squad builder and the sbc formation changed i didn't notice it at first so I did the whole squad by the incorrect formation and when I backed out to do something on the menu then got back to the sbc squad the original formation returned I tried to use the squad builder again and it changed to the formation it changed to last time I tried it with othe sbc squads and same thing and when I tried to submit it gave me an error I demand compensation
