Unity default fonts are changed after installing ubuntu-restricted-extras

I installed ubuntu-restricted-extras after a fresh 16.04 installation and then the font changed in certain areas of the Unity Interface:

-The Time
-Drop-down menus
-The application descriptions in Dash
-The top portion of a window (i.e. File View, Help, etc.)

At first I thought it was a fluke, but after a second fresh 16.04 install and installing ubuntu-restricted-extras, the problem occurred again.

This seems to have started happening in the past week so I assume a recent change caused this to occur?
