Waveform files

I recently had to trash my wavelab prefs. Ever since then when I render out CD tracks from a montage I get files ending in .gpk (presumably wave form graphics file?) along with the actual wav files. Although .gpk is needed for montages I obviously don’t want them for clients. Is there a way to stop Wavelab making these files for CD track renders?

This is the setting you’re looking for:

Thank so much Justin!
