Question for Heroes who Ursus regularly

I'm wondering if any other heroes experience this problem while fighting ursus.

I've noticed other classes being able to attack the horn pieces after reaching the 80% hp mark. But I know for me and my other friend who's a hero, we can't seem to attack the horns on most runs.
