Adding two/four regions below content above bottom first columns.

Hi,

When I place blocks in Bottom First columns in Mayo-Drupal7 they mix up into one block. I want them to stay separate boxes like they stay separate in Side Bar first and Side Bar Second. Can any one please help how to avoid this block mix up above footer. You may look my site here.. firmaroning.dk/brk

In case above is not possible I would like to add two or four extra regions in mayo theme below content region but above Bottom First Columns. Please see the Mayo theme regions picture attached for reference.

Any help is highly appreciated.
