Object pronouns lesson 2 error – Duolingo - Language Lessons Review

This app is great, I dislike the game model where points are earned and progress limited by the points. There is an ERROR in object pronouns stopping all progress where every answer is showing as wrong, although 2 of 3 are acceptable. I cannot advance because of this and am stuck here. Please fix this issue. Thank you.
