I feel I should warn you: I only have 4 characters, and only two of them are above level 2. So I don't think that is gonna make a difference, but hey, try it anyways. Let us know how it works. 
I also don't have the audio pack, same with several others, so please bare that in mind while you are testing.
Thanks for the update, I focus only on one character but actually I have quite a lot of savegames (apart from quick one) so I'd need to erase some them anyway

I only mentioned the audio pack because I remember it being downloaded as DLC via origin. It looked pretty weird to me, to be honest ( I mean, we all probably have native audio Eng version anyway, with subtitles).
I also tried messing with gamefiles (data from disc no.4 in my case) but it didn't help. I did it only because this game is distributed by EA and such weird things happen in their case from time to time ---> i.e. I fixed the commentary in Fifa 15 that way a while ago.
Well, it seems the only solution will turn out to be "to wait" anyway
