Can't Save Blueprints

Having a hard time saving blueprints once they're edited.

I click on Copy Blueprint, then Global.

I make the changes I want, and then Save to file.

But when I close the Toolset, and load it up again, when I click on the entry that I made, it reverts to all of it's previous properties.

For example:

I want to make boots of haste.

I alter the Resref, Tag, attributes and description to Quickfeet.

I save all these changes to the file - quickfeet.uti

Then when I open the toolset, or try to load the item in the game - it shows up as it's parent item - leather boots.

None of the changes I made have been saved.

I'm using the GOG NWN2 Toolset. Is there something wrong with my toolset that it isn't saving?
I've already enabled - Save to Global in the options.

Any help would be appreciated.
