Stock by Attribute v4.0 addon for v1.3.5-1.3.9

[Danielle]

I have downloaded the latest version and installed on a 1.5.5e store. I am having a problem with the display in the shopping cart. I checked in the shopping cart template file, but it has the right code. I can't understand why it's displaying the second "Out of Stock:" text when it should be showing "Available Stock:" with the available stock levels.

Also, that product has 1 in stock of size 6-12 month, and 2 in stock of size 12-18 months. The stock levels are synced in the admin. If I have 1 of the 6-12 and 1 or 2 of the size 12-18 in the cart, it displays fine. But if I try and do 3 of the 12-18, it is showing that the 6-12 are out of stock as well, even though there is only 1 of those in the cart, and there is 1 in stock.
