That's a limitation of the tracks not existing in the library and being called from the USB drive; the tag list is specific to the current library and your tags are not sync'd with those of the loaded library.
Hi!,
On my laptop I have all the tracks with tags and I can filter them easily. When I pass the tracks to my USB drive, and load them on another laptop or CDJ, I can not use the track filter option, although the column with the corresponding tags does appear (see image).
Anyone who can help me?

Not when using your export USB device connected to another user's library.
