There’s an * sign next to the mock-up page, what does that mean and how did it get there?
Sorry for the confusion with this @doreenw. The asterisks next to mockup names mean that something on that mockup has changed, and you have committed those changes to the server yet.
If you hit the save button, it will list all the mockups in the project with unsaved changes. Saving them should fix the issue.
Let us know if you are still having issues after saving the project.
I am also having similar issue .I have all the data saved but still cannot rename a file.Attaching screenshots.
