Program can’t be renamed in Mbed Studio 1.4.1. It allows to type a new name but after clicking OK, the name remains unchanged.
Thank you for reporting this bug. What platform are you on? Linux/macOS/Windows?

Windows 10. I observed that the problem is not consistent. Many times it works but not always. Before renaming tried changing the program from “active” to non-active but that didn’t help.
