Saved Filter Custom Columns don't display properly

If you filter down issues, then add columns and set everything up the way you want, then save the filter, the next time you click on that filter, all the custom columns go away. The only way to get them back is to click on the 'Columns' drop-down, click on 'Filter' or 'System', and then back to 'My Defaults'. Magically, the columns re-appear.
