The font on all Word documents has been changed and I cannot change it back.

For some reason, Word has changed all of my documents to a weird font/style. The top picture is the normal style taken from a pdf, the picture below is how every document looks now, including older documents. The strange thing is when I go to print the document or save as a pdf, it shows up in the "normal" format. Creating a document is now a challenge because as I'm typing, it is in the weird format, so things do not line up as they will show up. I have tried re-installing Word, making sure the style is "normal", and making sure the default font is what I chose, which is arial in my case. Notice is the "weird" picture how the spacing of the letters is also widen. Once again, all documents now show up this way.
