Video Files Names not Displayed on Metro Apps

Hi! When I look up some files on my desktop mode I can see all the correct info but when I look at the same folder using ametro app the video files are displayed but just as a black square. No name, no info, nothing to establish that is what so it gets very difficult to pick the one you like.
Is it an w8.1 issue or is only my Asus Tablet??



TIA!!!
