*** 'BUG' FIXED ***
We've confirmed that this problem is caused by having too many war spoils (the limit is currently 1000).
So for anyone who is reading this and has the same problem: check how many war spoils you have (bottom left of loadout screen). If you've gone over 1000 then that will almost certainly be the cause of the problem.
Hopefully Relic will increase the maximum limit now that the Brits have been released.
