Using,VC,program,,Video,files,become,duplicated...

I have used VLC program on my iPad Air 2 to play my video karaoke files with out problems, ok.

now I have purchased an iPad Pro, install VLC on it, load it with some video files but every time I turn this program off and on again, video files become duplicated every time by one more each time.

I have converted all the video files to VLC extension (xxxx.flv) like i did for my iPad Air 2.
