Pivot, Slicer and Timeline not correlating

I have an Excel spreadsheet with data spread over 6 months with the following fields:
�Incident no.�, �Date Submitted�, �SLA�, �Requester�, �Assignee�, �Site�, �Category�, �Summary�, and a few more.

I created pivot tables and charts for these, then proceeded to create slicers for each field and a timeline based on the �Date Submitted�.

All the slicers are set to �Hide Items with no data�, and they are all linked in �Report Connections�. The timeline is also linked to all the pivots in the �Report Connections� tab. All the pivots are set to �Refresh data when opening the file�.

My first problem is that when I select a date or a date range on the timeline, the charts update with the correct numbers, but the slicers do not change to reflect the same. Specifically the �Incident No.� slicer, shows all the numbers across the entire 6 months.

The second problem is, that when I select a value in one of the slicers, the linked slicers change to reflect the corresponding data except for the �Incident No.� slicer. For instance, if I select �Georgetown� in the �Site� slicer, the �SLA�, �Requester�, �Assignee�, etc. slicers, and the charts change to reflect the corresponding data but the �Incident no.� slicer do not show the associated incidents.
As an example: The number of incidents in January for Georgetown in this case is 8, but the Incident no. slicer does not reflect that, no matter what I try.

My objective is to build a dashboard with Slicers and charts so that if you drill down and select a date or date range, it only shows the incidents in that date range in the "Incident No." slicer.

Can Someone help, please?

I don't see any pivots, slicers, charts or timelines in that file?
