Problems with Made theme

We’re having some problems with our theme –

Firstly I can’t seem to add a Twitter feed or Mailchimp sign up list widget to our sidebar, when I do for Twitter it moves everything around on our homepage and creates huge gaps in between things and makes some things dissapear all together! Also under where it says ‘Twitter Feed’ nothing appears. And more the sign up widget there’s just a text box and no title like ‘maichimp signup’ or anything it’s just a really small text entry box and nothing else.

The other problem we’re having is with tags. We use tags to assign posts to certain areas on our homepage but they aren’t working correctly, is there somwhere these tags are set in the back-end other than in Theme Options as i’ve tried changing them there and am still getting the wrong posts in the areas on the homepage.

Any help at all would be much appreciated, I’m completely lost!
