BUG - Weight, 7-Day View missing days of the week. Instead showing variables "day.0.short" through "day.6.short"

Reported this bug through chat. After fighting with Joshua to have him verify on his end, he confirmed this is happening. He then insisted I take screen shots while he ended the chat.  Further chats have been more of a waste of time, and the phone number has a 2 hour wait.

I have verified on multiple accounts, web browsers, and even computers. 

It only happens on for Weight and only on the 7-day view, as this is the only view showing day of the week names that I have found experiencing this issue. Though given this is one of the few remaining pages on a different style it could be caused by many of the upgrades to the backend.
