Meeting showing "free" instead of "busy"

[pottert3]

Hello! We have a VA scheduling meetings. All of a sudden several meetings that she is scheduling are showing on the google calendar as "free" instead of "busy". I am sure it is a simple fix, but finding it hard to trouble shoot as I am not with her when she schedules them. The problem we are having is since these meetings show "free" my boss is getting double booked. Any advice would be great! Thank you!
