This may seem like a very simple question.

I've added a bunch of custom columns (CC).
I've checked them to display in the library book list.
However, each time I close Calibre, the program defaults back to the default columns.

Am I doing something wrong? Do I have to write a script to save this CC library? If so can someone point me to the instructions?

Thank you so much.
