In the post you linked, the fellow had gotten a replacement phone, which of course has a different serial number. Apparently TWRP will only "see" nandroids made with the serial number of the device on which TWRP is running, so it is understandable what happened there. He was able to copy the actual nandroid folder to the new serial number folder and use it.
In our case, TWRP is not seeing a backup it had previously made on the very same phone. Not sure what to make of that, as I would not expect a serial number to somehow change. But I suggested the same fix. Make a new nandroid, then put the originial nandroid with it in the same folder TWRP is currently using, and it should see them both.
