From the the backend I am consider as an Administrator and I have been responding to topics since "Overview". When a topic has been reviewed, it no longer appears in bold. This allows me to consider that the topic is treated.
But, for a few days, my colleague Swanny has been helping me on the Community as a Moderator from the backend. But there is a problem: when she responds to a topic it's always appears bold from backend (CF screenshot) I would like that when she responds to a topic this one is no longer shown in bold and considered treated.
How to do?
And if there is another way to work better from backend with different collegues can you please give me advices?

Thanks !
