Why can't I modify my Detail Symbol Styles ?

I am experimenting with modifying DetailingSymbolStyles.dgnlib to reflect what we use in our office. But it doesn't seem to work.

I have created a Default user and modified the file located at every place I can find.




No matter what I try, it always defaults to the delivered styles.

On the left is my modified Section symbol, and on the right is what happens when I create the section.

And this is what I see when I check on which cell is being used. The list shows all the cells 3 times.

Does this mean that it is showing the content of three files ? And if so, where are the extra files.

Is there something I am missing, and if so, what ?
