Failed exporting multiple

Hello, I recorded a long list of items and then splitted the recording to named tracks. Using arrows I can jump from a track to another and see the labels. When I export multiple (to mp3) it asks me to detail meta for track 1 then for track 2 them exports twice the whole recording.
What am I doing wrong?
Thanks!

now, tracks and export multiple works ok
