DGN to DWG export adds all turned off Levels

Hi Forum,


when i export from DGN to DWG, all the levels that i have turned off in various reference files turn them selves on?!?! why? and i cant find a settign that stops this.

i'm merging all references in the Default area, and preserving the self ref of the default through to the Sheet View, so as i collate all the info into one file from several as thats what we need currently, a simple email-able drawing for 3rd parties to look at and work on with all the hassle of references.

any ideas on a setting which stops all the turned off levels turning on? i can post my 4 tabs of the DWG output settigns box if it helps?
