The FAT filesystem used on SD cards can be implemented incompletely in some devices. (aka: sloppy, lazy programmers). The camera is likely doing a not-entirely-complete implementation which is acceptable for it, and some other devices, but the edge and probably many general-purpose computers expect the format to be managed better. I've run across similar problems moving media between some devices and computers. I've run repair tools on media that computers report corrupted and as soon as it goes back into the device it gets abused again (from the computer's point of view.)
