Could anyone please help with a problem with Traktor?

Hi all,

I've been having an annoying problem with Traktor lately. I've tried different versions of the software, the songs and even Windows already. It happens with about 20% of my tracks, so deleting all from collection and re-analyzing every time I start Traktor would take quite a bit of time. Please watch this video as I don't know how to write about it:

The problem reoccurs after restarting Traktor. I wouldn't mind not importing it to my collection at all, because that seems to be the problem, but don't know how to do that.

Thanks,
Bram

Sorry for the double post but I'd really like a solution.
