Hello, I just got the 4 pro and used the dji go 4 app for the first time. I made video and still camera customizations and then saved them to custom settings and renamed the 'custom 1' to 'starting pt'. i checked some settings and went back to custom settings area and the name was back to the default name. What am I doing wrong? is it the space on my new name....use no spaces or characters issue? Thank you.
