That's standard game mechanic. ASW attacks are priority and ASW capable girls always attack sub first. Only exceptions are BBV/CAV in yasen (because Zuiuns don't fly at night) and Suzuya/Kumano CVLs (which are "Attack CVL" - special subclass of CVL that attack surface targets first).

On the other hand it works both ways - if you have SS in your fleet she will aggro all shelling attacks from ASW capable enemies.
