%2D Specifics

When URL gets to Amazon buy page the affiliate id shows as MYAFFILIATEID%252D20 instead of MYAFFILIATEID-20. This issue is causing lost sales from any product selection because Amazon doesn’t give credit. A sale will only register if Amazon search widget is used. I have a WP plug that converts posts to pages & vise versa. Found an article that a says a Page will convert a URL to %252D while a Post uses the “-” so I converted Cart & Check Out to Post, but that only caused other issues so I put things back. My brain is fried on this issue. Please help.
