Text selection in PDF goes wrong in Adobe Reader

[RobertJanssen]

As you can see in the PDF below the text selection goes wrong in old an newer versions of Adobe Reader / DC.

The text selection works fine in Google Chrome PDF Viewer and Foxit Reader. What could be the problem?

I'm unable to upload the Word or PDF file here?

I opened the PDF with a text editor. The PDF contains:

<</Type/FontDescriptor/FontName/DBBWHF+Calibri/FontBBox[16 -9 6713378 52705]/Flags 32

/Ascent 52705

I've got the same PDF, but then a version were the text selection is OK. It contains this:

<</Type/FontDescriptor/FontName/DBBWHF+Calibri/FontBBox[0 -9 859 683]/Flags 32

/Ascent 683

Both PDF files derive from a Microsoft Word document. What could this be?
