The system has not been not updated yet. This is the case as soon as the statement line "xxxx points to (re)qualify" or "TC(Gold) membership valid until" line becomes visible.

I'd wait for a few days. The year changes are often a little slower than the monthly rollover. If the above-mentioned statement lines arrive and you still don't have what you're looking for, ring TC(Gold) management in Switzerland. I had similar trouble in 2001 when TCGold started, despite a few anomalies in the system (trouble with club miles / bonus miles) in the qualifying year 2000, my status was changed "manually" to TCGold straight away.
