WaveLab Pro 13 renaming bug?

Hey there,

I just got my master done and wanted to export a new version with a completely different and unique name. Somehow WaveLab always exports the audio use the name from my last project, which is not even in this session. What is happening here? The names are clearly different.

Please help (using latest WaveLab Pro 13)

Can you try rendering from the Ribbon to see if that makes a difference?
