Name user backend

Hi there,

I hope someone can help me and I would greatly appreciate all comments.

After updating to the newest version of wordpress the name of my users is not visible anymore in the backend. A sur- and lastname needs to be filled in to get it to show in the backend. If only one of the two is filled in the name will be displayed as —. I want to display whichever is filled in.

I hope you understand what I mean. Thank you for your time in helping me.

regards,
Sophie
