Product description & terms – PayPal payment page

Classified Theme
Version 6.6.7
Standard PayPal enabled
my site: https://usedmotosports.com

Currently I have two types of listings,28 day Private Seller & 28 day Dealer with two types of enhancements:
1. Front Page Exposure $2
2. Featured Listing $1

What I’ve noticed, see screenshot, is when paying for the listing via Paypal the description is correct. (meaning showing the correct listing) but the TERMS are what have me confused. No matter what combination of enhancements or listings the terms state “for each 4 weeks”. (4 weeks is probably referring to the 28 day listing length)

I’ve looked thru PayPal and the sites Language and cannot determine how to change this to something more flattering like “for your listing”.

Thanks
