Scheme (or CMS itself?) not working properly

Permalink Browser Info Environment
Editing content is nearly impossible, as line spacing, font attributes and other formatting is not consistent between edit mode and user view. When switching to HTML view, identical formatting tags ar oftenly contained twice or even three times.
Sometimes after editing content and saving, the respective area suddenly is completely empty. Two developers spent hours with searching forums and trying to find solutions. I#m sorry, but we cannot use concrete5 with this theme for our project.
Purchase date was 4 days ago, I released the license from the project. Please refund, thank you!
Best regards
