Cubase 7 le export help

Hi, I had a problem exporting my song out of cubase. I had mixed midi and audio tracks and leveled them in cubase because the midi tracks were too loud. When I exported the track it didn’t keep all the changes I had made to the levels. It keeps the slider at the same spot but I have to move the slider a little bit to make it put the change back in. Now it happens when I reload the song of if I switch off the screen and come back to it. Thanks

I understand the whole midi isn’t audio and you can’t just send out a midi file except I did that and the file was on my recording, it was just too loud and I can’t make it stay quiet.
