Because this never happend to me before and I tested it several times now after this happend. More career progress does NOT fix this problem!

You can complete as many series as you want, this will not work.

Not start an archived race is an option, but the only fix (for now) without losing any progress is indeed, as you pointed out correctly, to have more progress than when you used the car in another SE or FB event before.
