Currently when you have a CN open in non-edit mode (filter by selected components is not available in edit mode for some reason) with 'Filter by selected components' selected and then click 'Redistribute Items' the redistribute popup comes up, you ok it, and then the filtered BOM disappears - it doesn't become unfiltered, it just disappears. If you click into the drop down, you can see that the option is still selected. In order to resolve the issue, you have to click to disable filtering and then click again to re-enable it.
Ideally when Redistribute is selected, the operation would be carried out without the BOM disappearing afterwards. Either whatever it does to make the BOM vanish should be fixed or the Redistribute function should automatically toggle the filter option.
