Missing tracks in LMS

[tank121]

I recently ripped BBC Radio 1 Live Lounge Volume 6 using EAC but the CD was not in Freedb So I used one of the plug in's for the tag information.

I used Mp3tag to format the track information.

Album showing as either -
BBC Radio 1's Live Lounge - Volume 6 [CD1]
or
BBC Radio 1's Live Lounge - Volume 6 [CD2]

Not all the tracks are showing in LMS, numerous ones are missing.

This is the first time this has happended to me, I've attached a pic of the mp3tag screen. All 40 tracks contain the same amount of tagging information.
