When one put a worksheet or a dashboard onto a story
and change something in it, its' "state" (including filters,
formatting, annotations etc) become "frozen" of a kind --
one could change something on a story point, but those changes
doesn't propagate onto originating objects (original worksheets / dashboards).
This includes Quick Filters, which could be set originally as common
for the Selected Sheets or even Datasource(s), but would have no effect
when changing after a worksheet has been included into a story point.
Hope it could help.
