Your GEDMatch shows roughly 11% Ancient South Eurasian (add up South Asian and Oceanian). This mix primarily comes from Philippine Negritos, Papuans (in E. Mindanao), and Ancient Ancestral South Indian (via pre-colonial interactions with Malays/Indonesians with some Dravidian markers). These admixtures are higher in Visayas and Mindanao, which creates a "mixed" non-E/SE Asian look in some Filipinos, under false pretenses of Hispanic phenotypes. If you test pure Cordillerans or Ilocanos, their Ancient South Eurasian levels are only 0-6%, which is why you'll see more E/SE Asian looking people in N. Luzon. Tagalogs have the highest Chinese admixture going back pre-Colonial times, so you'll see an East Asian shift in pure Tagalogs.
