tags lost after a crash

if i edit tags (specifically bpm) and while working a mix say MV crashes, the bpm tags that I edited are lost....
I thought once I go through the pain of editing the bpm and hitting Alt+M S S {Enter} the tags is saved..... apparently NOT so. Maybe the TAG is written but the file these files arent saved and should a crash occur whammm... I have to go back and redo all those lost tag. I'm using MV Pro6 version 6.394
