Sometimes two macros in the same workbook and module will display differently: one will show just the Sub Name, the other will show the FileName + Module Name + Sub Name.
Depends on if you have macros of the same name stored in different locations/modules, and/or which workbook has the file. Macros in regular code modules of the active workbook should only appear as the simple name. If macro is in a different workbook, will show longer name.
