tracks deleted from the collection and hard disk still appear as missing when starting rekordbox.

Hi Everyone,

I've been dealing with a problem that is driving me crazy, I've deleted 2 tracks from my collection and also from the folder on my hard drive where I have stored all the tracks, but every time when I start rekordbox and click on:

File -  Display all missing files, 

these 2 tracks always appear there, during the synchronization with my usb also appears as it was not possible to synchronize all the tracks and these 2 tracks also appear there. I have searched the files all over the pc and there is no trace of them.

Why rekordbox keeps warning me that these files are missing?

Hope someone can sort this out. 
 
Thanks in advance,
