Issue/Introduction

After refreshing the page on the MUX Project Tiles, the Project Timeline displays 'undefined' instead of the Project Start and Finish dates.

STEPS TO REPRODUCE:

1. Login to MUX and open the Project Tiles workspace.
2. Duplicate the tab
3. Look at the project tiles. You see the project timeline with Project Start and Finish dates 
4. Refresh the Project tile tabs. You might need to do several refreshed in one of both of the tabs.

Expected Results: The Project tiles load correctly

Actual results: The Projects display 'undefined' instead of the project dates under the project Timeline 

The Developer Tools Console displays the following error:

Uncaught (in promise) Error: E_DEFAULT_LOCALE_NOT_DEFINED: Default locale has not been defined.
