If certain buttons are not functioning normally, or assets and jobs are not loading correctly, you should first try Resetting your User Interface (UI).
You can do so by clicking on your account name at the top right of the browser page, next to the search bar and above the view buttons.
When the Settings box pops up, click on the "Reset the user interface to the default settings" option.
You will be logged out and taken to the front page, and asked to log back in.
NOTE: The shortcut for this feature can be accessed by holding down COMMAND + ALT + SHIFT + R simultaneously.
