I have about 10 manufacturers in my eCommerce module. When I needed to change one from "Manufacturer" to "Manufacturer Two", it would allow me to type the change in, click the save button, but when I click Update Attribute, nothing happens. If I leave the page and come back, the changes have not been made.

This has happened multiple times. Some manufacturers I can change and some I can't.

I now have hundreds of products added so I do not want to have to add a new manufacturer and reassign this new manufacturer to all associated products.

Any ideas?
