Dax Color Conditioning not working for all Rows

[jaji]

Hi guys, so I have this conditioning in DAX: 

Task =

SWITCH (TRUE (),

    'Table'[Date] < TODAY (), "#FD625E",

    WEEKNUM ( ''Table'[Date], 2 ) = WEEKNUM ( TODAY (), 2 ), "#FFD86C",

    WEEKNUM ( ''Table'[Date], 2 ) = WEEKNUM ( TODAY (), 2 ) + 1, "#73B761"

)

And I apply this Dax to my table in Power Bi Desktop. It worked floorlessly, till an update and now some of the rows don't reflect the condition. The condition is applied to ALL COLUMNS in the table; All, except one column, "Custom" dont seem to reflect everything. The rule should apply Irrespective of what's in that column, since ''Table'[Date] is independent from these columns. The first four columns aligns with what i did expect with the coloring but the 

Have anyone come across this problem?

We realized that when the 'Table'[Date] column defaults to 1/1/1900 due to an error in the date, it breaks the color conditioning (or the color condition don't work properly). The Problem resolved itself the moment that was fixed from the source file. Thanks!
