The only simple reason for your issue is that the camera of your system is not able to communicate with SD card properly..U need to contact officials to solve your issue...Regards

Have you tried a fully formatted card, are the contacts on your card or cards worn out. do you think the camera's contacts are oxiadized and need cleaning? those are some maintenance options that can be looked at. cleaners. sprays and filter papers can do the trick if you know how to clean.

If it still doesn't recognize the SD, try the above steps with a different card. If that doesn't work, contact the seller to get an exchange.
