Slicer using filtered Hierarchy

Hi Ankh-Morpork ,
According to your description, you can either create a new table or create columns on the original table following the logic of this table creation

Table 2 = 
SUMMARIZE(
    'Table',
    'Table'[Lvl 1],
    'Table'[Lvl 2],
    'Table'[Lvl 3],
    'Table'[Lvl 4],
    "Level 1",
    IF(
        CALCULATE(
            SUM('Table'[Responses]),
            ALLEXCEPT(
                'Table',
                'Table'[Lvl 1]
            )
        ) >= 10,
        'Table'[Lvl 1],
        BLANK()
    ),
    "Leve 2",
    IF(
        CALCULATE(
            SUM('Table'[Responses]),
            ALLEXCEPT(
                'Table',
                'Table'[Lvl 1],
                'Table'[Lvl 2]
            ) 
        )>= 10,
        'Table'[Lvl 2],
        BLANK()
    ),
    "Level 3",
    IF(
        CALCULATE(
            SUM('Table'[Responses]),
            ALLEXCEPT(
                'Table',
                'Table'[Lvl 1],
                'Table'[Lvl 2],
                'Table'[Lvl 3]
            ) 
        )>= 10,
        'Table'[Lvl 3],
        BLANK()
    ),
    "Level 4",
    IF(
        CALCULATE(
            SUM('Table'[Responses]),
            ALLEXCEPT(
                'Table',
                'Table'[Lvl 1],
                'Table'[Lvl 2],
                'Table'[Lvl 3],
                'Table'[Lvl 4]
            ) 
        )>= 10,
        'Table'[Lvl 4],
        BLANK()
    )
)

Setting is not blank in level 3 page filters
Final output
