Studio 2015 bug: PDF export creates DOCX file *with .pdf extension*

Question

I have a project where I have added a PDF source file. 
 When I run Batch Tasks -> Export files, I get a .pdf file that doesn't open in a PDF reader. Closer investigation shows it is a Word DOCX file, only with the wrong extension! 
 That it is a DOCX file is consistent with the way Trados Studio always has worked as long as I know it: It transforms a PDF into a DOCX and then continues from there, also exporting to DOCX &ndash; which is very adequate, too, since that way I can continue polishing the final document. 
 The only bug, then, is that the output files get the PDF extension. 
 This is Studio 2015 with Service Pack 2 and the latest updates, version string 12.2.5087.4.

You are right, this seems in fact to be a bug. If one saves the files using "Save as target", it is correctly saved as a .DOCX file, but if one saves it using the batch task "Export files" and selects "Target" as file version, the file gets saved with the file extension .PDF, although it is in fact a .DOCX file.

Just a quick note... this is already logged for resolution with the development team. So it is a known issue.
