Export Directory

Recording Audio Books I like have the export directory set in preferences as each chapter needs to be recorded separately. Recently I recorded an audition and in the export dialogue changed the directory.

The directory in preferences is still the same I had set before but now when I export it is ignored and the one I used for the audition is used. Why bother with preferences. I have changed it back on my next audio book export in its dialogue box but shouldn’t have to do that
