Having read your post again, I may have got you further on than you actually are.
If you haven't seen your mapping changes (if you have any, most people have) there will be entries in the message box on the "Your Business" page.
You need to start on the "Land" page to view the info they have for your business, after reviewing this go to "Land Use" page and make cropping adjustments.
When on "Land Use" page you can click the 'pen' symbol to edit, 'add' to add new lines in that particular field, or 'Del' to delete that line.
When you have completed this correctly for every field, there should be no 'Orange' coloured boxes on the screen.
Now you are ready to go Apply for BPS (see above)
