Khaos Starsource Dragon does not activate it's effect if summoned using opponent's monsters with Super Poly

YGO Omega Bugs

Description: see title

Steps: play Super Poly (and if i’m correct, any fusion effect that would fuse using only your opponent’s dragons), and summon Khaos Starsource Dragon using two light or dark dragons (say, two bystials like Lubelion and Saronir) owned and controlled by the opponent

Expected result: Khaos should be able to activate. The issue right now is that Khaos does not activate its effect to destroy equal to the materials that are light or dark.

This bug happened repeatedly while playing in W10.

Not a bug. The scripts follow OCG card text, and the OCG text states it only counts your monsters that were used as material.

“①: If this card is Fusion Summoned, you can target cards on your opponent’s field up to the number of your Light/Dark monsters used as Fusion Materials. Destroy that card.”
