Rss from feedburner to wordpress not working

I am a new wordpress user and bought the thesis theme from https://diythemes.com/thesis/ I believe I have everything installed correctly but my feed isnt working. I already had a godaddy blogsite for blogs and our podcasts https://www.realestate1370.com . I did not want to change our feeds as my podcast are ranked #7 on itunes for real estate investing so I have rss from my blogpage https://realestate1370.com/rss2.aspx to feedburner https://feeds.feedburner.com/RealEstateInvesting101. On the thesis theme options there is an option to enter in my feedburner feed https://diythemes.com/thesis/images/thesis-options.png, I believe I have entered it in right but still isnt working… Does anyone have any ideas?
