Reply to BPM in Library? Showing 0...

Hi, Could someone just give me a link with help :P or explain why sometimes my files in the library showes 0,0 bpm, but when loaded it showes in the deck?

Tried to google it, and saw a post here but no seloution on it:/

Strange thing is when i have a folder and add it as an playlist were some files show 0,0 bpm, and then reanalyse when the playlist is selected the bpm showes in the library to:| but not everyone thou, and sometimes when i go to edit after i loaded the file, and then press restore and ok, the bpm showes correct... makes no sence to me:P

i got VDJ 7 installed as well, dont know if this got something to do with it...
