Saving as STL - SolidWorks automatically re-imports it?

SolidWorks 2019, SP1.0.

Previous versions of SolidWorks:

1. File, Save As, STL

2. File exports to STL, workflow resumes.

2019:

1. File, Save As, STL

2. File exports to STL

3. SolidWorks opens the New Document dialogue (select a template/material)

4. SolidWorks automatically seems to re-import the just exported file

My question is, why is this behaviour happening? I can't find any setting anywhere to disable it, I don't need to see what I just exported again...

Thanks,

-Iain
