The clssifieds plugin is a trainwreck!!!!

All i get are short codes on my pages, no categories, there is a list of categories in a drop down menue for posting a ad. it does not show parent category. So if there are two subcategoiers under different parent categories they look double. example
Help wanted <<<<<parent
editing & writing <<<<sub
service offered <<<<parent
editing & writing <<<<sub
****On the create add page the drop down ***menu reads as follows:
editing & writing
editing & writing
help wanted
service offered
****There is no seperation between parent ***or sub categories.
1. How do i fix this!
2. Could you please start providing better manuels with your product. Please!
Thank You.
