File->Refresh will only refresh modified Library data from the Library into a client tool. It doesn't actually update data on the objects themselves.
The Supplier data is added to an object (eg a device or connector) when the Library Part is first assigned. After this, if you make a change to the data in Library, you must update the object itself. To do this manually for an object, you should select the Update button (shown in the following image):
If you have many objects in a design that need to be updated, you can use the action Action->Update->Batch Update Library Parts
