PDF text appears wrong on my computer but OK on another
I have received a PDF file from someone in an email and when I open the file from the email or after saving to hard disk, it appears like this in Acrobat Reader DC:

But if I open it on another computer in our office then it appears correctly in Acrobat Reader DC as:

In my office two computers show as mine and three can open the file OK. The two computers also have "Acrobat X Pro" installed and so also have 'Adobe PDF' printer driver. One of these computers is Windows 8.1 and the other Windows 10.
The three that load the file OK, are using different versions of Acrobat Reader and different versions of Windows.
Any help in seeing what settings may cause this display error.
