Editing the txt file for x instead of X will effect all NEW WF beams you load into a project only. Once a family is loaded into a project file, it becomes part of that file. They don't "reload" each time you open Revit like an autocad xref does (that's one reason Revit files get so large). Fastest way I found to change the existing beam families in your project is to just expand the Families section of the project browser, and under Structural Framing, expand the "W-Wide Flange" section. There you should have a list of every beam size loaded in, showing the uppercase X. Just right click on each one and pick Rename, and change it to lowercase. You have to do it individually, but it goes very fast - only takes a minute.
