The Filename in the Assembly Browser Tree and the Component don’t match.
When renaming or copying and replacing parts in assemblies certain workflows can lead to a mismatch between the displayed part name in the assembly tree and the actual part name. This is easily corrected thanks to the Productivity tools. Go to the Assemble tab, Productivity, and then click on Rename Browser Nodes. You then have the option of selecting Filename, Part Number or Default. Selecting either of these won’t change the part attributes, only the attribute that is displayed in the browser, and all of the components will be updated simultaneously.
