send sequence to audition errors/problems

I ve been trying to send a sequence that I have been working to audition so i could mix the audio better

but for some reason

i get a session with empty clip on track 1

i know I can export omf and aif but its just annoying to me that this is happening I used to use that feature with no problem

I dont know if its me or the software, if anybody knows could you please post a solution

thank you
