This shows the date as 2013. The start was 2011 as shown on season 1 of the series.
I looked here: https://www.themoviedb.org/tv/36994-workaholics and it got changed recently, no comment. I requested a change there to reverse that edit. If there is nothing you can do until it is changed, I understand. However, this at least informs you of the issue and the status of the data source change.
Looks like it auto updated already. It will refresh the next day after making edits. Thanks.
I was able to make the change on the mail date, and per my report, TMDB has corrected the dates on seasons 1 and 2, so all should be good for your sync of data at this time.
