My System preferences always opens in a small window now.

Every time I open up system preferences it always opens in a little window. All lf the text and the icons are all scrunched together. I'm actually an IT person and have been doing this for years but for some reason I can find nothing on the internet addressing this issue. I've looked at the view settings, window view settings nothing seems to address the issue.

The green button is missing to even expand it to full size. It is very annoying and I can't seem to find a resolution.
