Hello Andrea,
"Test_Pro" is the camera name that is recorded in XMP of the images from this camera. In Metashape XMP has priority over EXIF data.
It seems to be an issue of DJI firmware, so if you have any contact in DJI, you can let them know, that the camera name is incorrectly kept in XMP meta data.
I've seen recently similar problems for this camera/drone coming from other users.
