xml for FCP7 thru 7ToX problem

I exported xmls for FCP7 ( shoot with zaxcom nomad and blakmagic cam) .

The XML went thru 7toX software to be edited in FCPX .

The editors tell me that he got my only fisrt mix track duplicated instead of my Iso…

Did anyone experience the same thing? bug? operator error?

Thanks,

Lucas
