Date Slicer auto update not happening on start date with Last week as Default setting

[AryaKrish]

Hi,

My date slice is on Preweek (Import mode Date table from Db).

Created a coumn to mark 'Preweek' and rest dates as 'custom' - applied this as a visual filter.

Report is on daily refresh but every week ie Mon I can see the dates slicer showing 14 days 

- The start date is not getting auto update , I have to click on clear selection for this to change 

I have a toggle button with bookmarks to Preweek and Custom Date. This display of extra dates is confusing users.

Please help with this issue.
