On a Linux Mint 18, I created a file using WPS Writer. When I opened that same file on a Windows computer using MS Word, the spacing between two lines didn't apply.

In the original file, I modified the "Normal" style in the document by making the spacing between lines 0 pts. When I opened the document using MS Word, there was still 6pts or 9pts (I can't recall which) of spacing between lines.

Why is that the case? Why didn't my original style carry over?
