Insert Symbol pulls in old symbol

We have revised some old symbols that used to be Upper/lower case lettering to be all Upper case lettering. The old symbols are relocated to another directory, not under the current pro_symbol_dir defined in config.pro. When we go to select the symbol, the preview window shows it like we expect, all upper case. When it is dropped onto the drawing, it becomes the old Upper/lower case symbol. Using Windchill, no other drawings in the workspace or loaded in memory as the user erases all not displayed between drawings. We are on Creo 4 m080.

What would cause the system to grab a symbol from another directory that is not even a sub-folder of the main directory defined by pro_symbol_dir.

The really confusing part is that sometimes we will get the all uppercase symbol.
