Wavelab 12 Pro renders multiple files into multiple groups? Help!

Hi, this is an issue that did not happen in v11 Pro, but when I render multiple files and want them to open in their own group, it puts each file in a separate new file group, instead of all of them into 1 new file group. This is kind of a pain when rendering dozens of files at once. I cannot find a setting that seems different from my v11 setup - am I missing something? Please help!

Are you using WaveLab 12.0.50 ?

12.0.51

You are right, this is a bug, sorry. This will be fixed in the next update. I therefore recommend disabling this option in the meantime.
