Hi Karine,
Thank you for reaching out and sharing the screenshot asked by Ares. I am unable to reproduce the similar behavior at my end. I am able to change the name by double click and it remains same once I rename the character style.
Would you mind trying sharing the OS and XD version of your machine? Is it happening with all the files or with a specific file? Have you tried checking the latest update to your grpahic card drivers?
We will try our best to help.
Thanks,
Harshika
Well, I think I sorted out part of the problem. It was originally a Sketch document, the same issue happend with all the converted documents, but when starting a new project from scratch I managed to change the name in list mode. I have the OC Catalina 10.15.2 at the moment and updated XD. Uninstalled and reinstalled it yesterday. Problem solved for me this time, but it would be good to be able to work directly with my old Sketch files.
Thank's for your time 🙂
