Error synchronizing file system listing of SD Card on Windows PC via USB

I'm using a Huawei P8 with a MicroSD Card to store my cam images and everything works correctly until today.

I found that I can list all the pictures/files from the "gallery" of Android in my local SD files, but when I connect the SD Memory to my PC via USB and mount the FS, I can explore all the tree of the filesystem and also the path where my files are located, but can't see the last 24 hours files I created with my cam.

These same files can be listed in the "Gallery" of my Phone, as well as I can check the same INTERNAL PATH of Android FS that I reproduce later in Windows Explorer without seeing the same files there, but I can see in Windows the rest of the files of that same SD directory.

Anyone can give me some light on this, please?
