What is going on with titania

I don’t know what’s going on but I would over half the time I use a special 3 and try to heavy chain in the corner with Titania the AI will throw their special making the whole sp3 rotation useless. I never had this before. So is there something going on?

It's actually 4 but i rounded
Enemy will have lots of debuff and they will hold block in corner, just chain heavy on and on till you win.
