Timeline/Slicer refresh issue

Hi all,

I've provided a sample workbook to show my issue which has been ongoing for a while now however I've not been able to find a quick win and it's driving me mad as I'm sure it should be very straightforward.

In my head I thought I would be able to use a change or click event for the timeline to then refresh all to resolve the issue but I've not had any joy. (That's not to say that wouldn't work but I'm probably doing something wrong)

Basically, I want to use Timelines along with regular slicers however when the timeline value is selected, changed or cleared, the slicers do not refresh to show the new available options.

The Blue figure is what happens, and the Orange figure is what should happen.

Thanks in advance and fingers crossed.
