Welcome to the Q&A Forum

It looks like the url's being shown are unique categories. I don't know if switching to a flat url structure will help, or just change the url-ref (rho-1..). I think Magento (at least community) needs a better canonical handler than what is built in, I find that Ultimate Seo from Mageworx takes care of most of these issues including ones caused by pagination and layered navigation. If these are unique Categories, then unique content should be created or you will need to overwrite the default magento canonical's with a module and point to one Rho category. You might also want to consider making 'Collections' apart of your layered navigation instead of creating unique categories for each shopping style

Thank you all for your responses.
