Slicer item with no data (blank) is showing why

[drom]

Hi and thanks in advance!

I have a TABLE, not a Pivot Table
This table is huge, so I have say 2 Slicers
The First Slicers named "QAZ" shows 3 options:

AA
BB
CC​

The 2nd Slicers named "Country" shows 5 options:

Spain
Italy
UK
Ireland
(blank)​

When the Table is Clear with non filtered data, there a re not blank items for the Column "QAZ", I mean the 1st Slicer named "QAZ" does not show blank items

If I select using the 2nd slicers the option(Blank) then the 1st slicers shows only the posibility "BB"

which is actually OK, because the option BB has some cells with no country

However when the Table is unfiltered if I use the first Slicers to select "CC" or "AA" then I have the possibility to select blank from within the 2nd slicer

but oviously if I select the (blank) option the Table shows nothing

What am I doing wrong and/or how can I avoid the Option (blank) if I know I do not have any

I mean why I am still having the Possibility to select (blank) as country when the Column "QAZ" for the option AA or CC does not have any blank country

ps:
I do not want to Use additional Columns and/or Slicers, VBA and/or
I am trying to know why this is happening
