Well after trying it myself as well, it happens to me as well. At SIN
, in my 777 they vectored me into 2L I think it was. I had my APR switch on and everything, but the way they vectored me, my 777 had to turn like a fighter to get lined up. I had to TOGA and the vectored me around again...this time almost straight in. The AP
got hold and it tried to line me up with the taxi way.
So I tried it at HAN also in my 737BBJ. Same problem....Not sure whats up with that, if anyone has a clue please let me know.
