Now, I had/have the same bug with not adding goals and assists.
At CL-final Achauer scored 4, assisted one.
At squad view (line up -> stats), 3 goals were added, no assists.
At club history, no goal and no assist were added.
but... there are missing two more goals. I made a summery of the goals at line-up and the result: 242. So, 3 are missing (one is Aschauer from today)
