Problem text widget sidebar arras theme

Hello all, I really hope some can help me with this problem… I put some text in the text widget within the primary sidebar of my Arras theme but i have a very strange problem. The text I put is correctly displayed on all pages of the website, but NOT on the homepage. How is it possible to have a difference between the Homepage and the rest of the website pages, and how can I solve this?
The URL of my website is: http://www.brusselscity.net, look at “Video of the month”. The text/embedded video displayed on the homepage is something I deleted and replaced by the text you will find on all other pages of the website.
Thanks a lot already for your help!!
