Saved Filter rewritten when adding column with sort order

In Task Inbox perspective, Column order for Saved filters get corrupted when user changes columns in following way:

1. activate Saved Filter 'Active'
2. deselect all the columns
3. add Id column
4. click to sort the Id column
5. click Save Filters, set a name
6. see that the original 'Active' filter has same column config as the new filter

Probably affects also other perspectives.

The original Filters' column settings can't be restored even using the Restore Default Filters button.
