Yellow warning triangle on Event Library

I have read previous posts about this issue but am still having problems with a nasty little "yellow triangle" in the event line which I can't seem to be able to get rid off. I have tried the "relink", there is no problem in the timeline and the file that did show up in the "relink" is there in the .fcp bundle package. Hm! What next can I try? I would certainly be open for suggestions thank you. Constructive that is!!!

Since misery loves company, may I say that I have had the same problem for a long time now with no solution. I never find anything wrong. My exported projects seem to suffer no ill effects. But – dude! – this is worrisome and annoying because you never no when the cry "Wolf!" might actually be a valid warning!

the haha. How right you are. You never know when it might be the real thing. But thanks for letting me know that I’m not alone with this problem. I just hope it all turns out well in the end
