Annabelle: Creation (2017)

Continuity mistake: When Janice is on the stairlift on the second night, just as the stairlift stops, we see her looking over the arm of the seat. Camera changes and and she is no longer looking over the arm. (00:49:00)

Question: How was Annabelle still using her powers behind the door? She led Janice to finding her and freeing her, so even in the blessed room Annabelle can still use her powers?
