Expression Web Auto-Increments Values of Name attribute for input tag

Hello everyone. I'm new here. I have a problem with Expression Web.

I have more than a hundred pages created from my self-made template. My website sells products so I subscribed to RomanCart for my shopping cart. In my pages, the cart is part of "Editable Region" but everytime I update something on the template, the VALUE for NAME increments itself. For example:
after the update, all "storeid" have number suffixes like name="storeid0", name="storeid1", name="storeidX".

It creates a big trouble especially when I publish the site and forgot to change all "storeidXX" back to storeid
