Because Ayu played the pre-qualifying round and won the first series and was a semifinalist in the second series, and thus was awarded with a WC in the Main Draw. Another 2 WCs in Qualifying Draw goes to Sandy Gulmuya and Nudnida Lauagnam from Thailand.
Wynne Prakusya, however, did not join at all and thus did not get the WC. As Wismilak has upgraded to Tier III, many good players start joining the tourney, and thus, the WCs are given in such way.
Anyway, if Angie gets to the MD with her rank [which I hardly think she will just because the cut off is top 70], Wynne will get the WC.
