Display of dropdown slicer changes when move back & forth between tabs

[Vauban]

Hi to all.  Very much a rookie here.

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.

Any insight appreciated.
