Brigadier Font Issue

[Wslatts]

After recent lollipop update, menus popped up prompting my husband to answer. Not sure what rabbit hole he went into, but now the font has changed to this bubble style in various places such as messages and some response areas in basic menus. It seems like an issue with default font, but settings only allows change in font size, but not actual font. Have looked into settings within apps to try to find a way to change font with no success. Anyone know what happened or how to fix?
