Sublab vs Sublab XL Price

When I looked at the prices for Sublab and Sublab XL on the website, it says that Sublab XL is $50 (discounted from $80) and Sublab is $60 (discounted from $100). When I added both to my cart, however, it said that Sublab XL was still $50 while Sublab was only $40 (as I believe is intended). What is the actual pricing for the plug-ins, and is there someone working to fix this?
