Pivot Group by day is out of order

[CascadeDiver]

Hello,

I have a Pivot Table where I group data by 1 week (7 days). However the groups are jumbled up and no longer in any sort of order

I'm not sure what the deal is. Does anyone have experience with this?

Solved..ish

I removed the A-z and Z-a sorting and that fixed the issue. However I don't know why the issue was there in the first place.

Now, the slicer and the table are mismatched. The table is sorting correctly, without utilizing any filtering. The slicer is showing the incorrect sorting such was originally the problem. But I cannot un-sort the slicer.
