There was a bug in the old Honeybee_Normalize by Floor Area. If you update your components to the version on the github, you should see correctly normalized results. Otherwise, you can just take the raw non-normalized results and they should be correct or you can use the color zones component as @mostapha suggests, which will perform the normalization correctly.
Also, that example file is way more than what is needed to recreate this issue. Please follow the forum guidelines in the future (Ladybug Tools Forum Guidelines)
