DAX Measure won't return a proper result

Hi,

I'm struggle with this easy measure and I can't figure it out what's wrong. I've tried all filters combinations and still get the same result as soon as I add hours intervals. See pictures below:

That's the measure I use atm for Sales Qty

VAR vFilterContext =
FLOOR (
    LOG10 (
        SIGN(ISCROSSFILTERED ( 'Merchandise Structure') +
             ISCROSSFILTERED ( 'Articles') + 
             ISCROSSFILTERED ( 'Product Lists') +
             ISCROSSFILTERED ( 'Promo Classification' ) + 
             ISCROSSFILTERED ( 'Sales Classification' )) * 10 + 1
    ),
    1
)
VAR vResult =
SWITCH (
    vFilterContext,
        0, SUM('POS Sales'[Sales Qty]),
        1, SUM('Sales'[Sales Qty])
)
RETURN
    vResult

Also, I've tried different measures using all filter functions so far. What am I doing wrong?

Please, help!

Thank you!
