I have copied and pasted a drop down slicer from and to the same tab.
The slicer looks just the same as the one I copied from.
I save the pbix file.
Up to this point all five drop down slicers look the same as the four on the left in the slicer picture below.
I then click to a different tab.
When I click back to the previous tab the default display for the new dropdown slicer on the far right is showing as seen in the second picture below.
I have looked for differences between the various attributes of the Permit Sub-Type and the other four dropdown splicers and I can only see one difference. That is that a new attribute shows itself once I come back to the first tab in the General attribute section - the Orientation field. For lack of another reason I'm thinking the slicer upgrades itself when I go back and forth between tabs. Regardless, where can I go to change whatever attribute so that my default shows as "All" like the rest of the dropdowns.
