I changed the default filename character replacement so that a : gets replaced with a *, meaning that the colon should be removed from the filename. When ripping however, this does not occur; despite having changed this colons are still replaced with semicolons just like in the default options. I double checked that my changes were kept in the menu and they were, I even tried restarting the program. Once this issue is fixed, I would also like to know why it is not possible to replace filename characters with two-character combinations. I would really like to be able to replace colons with a space and a dash, but only one replacement character is saved each time so I can't do this.
