Saving Session Copys From 10 to 9

Im having the worst time right now to deliver stuff cause they ask me sessions in pt 9 and i work in 10 but the problem is that i want to just save the session file (.ptf) with no audio files at all, i rendered all my clip gain, and in the session setup i have the interleaved option disabled.



is this a bug or im missing to comply with another pt spec for compatibility



help guys i know you are wise enough
