1.2 wrong file sizes reading

Just noticed it recently, dont think it was a problem in earlier versions, the size, numbers shown in status are all random and wrong.Suddenly the overall collection "reduced" in size by 50 Gigas- as read by Traktor
for example 1154 songs 9.1 hours 1.2 G while it should be 13,7 G and whatever days, not hours.
It all led to me re organising, restructuring which though for wrong reasons, was good thing.
I just wonder if only my collection got messed up somehow or it is general bug.
If former then any tips how to clean/clear it up ?

 

What about the number of tracks, does that stay constant?

 

I am not sure, if it varies then little but somehow the collection size goes up and down? It used to be around 200G, now it shows, changing randomly from 160 to 180G. Couldnt find out anything from NI as all the DJ support people are on sick l;eave.
It is just all weird, no issue in practical sense really but, you know, it is good to know why.

 

I have the same Problem!
When i put traktor 1.2.1... later i clean some folders...so i waiting when i come back to traktor to saw tha there were missing tracks...but there weren't.
The numbers of trucks were the same...and when i wan going to the foldiers which i were i had deleded there weren't the tracks,,,,but down the info said tha i hadn't deleted tracks...
