Calculate Dynamically Change Duration

Eesa , Assume you have independent date and time slicer (not joined with table)

measure =
var _sdate = minx(allselected('Date'), 'Date'[Date])
var _edate = Maxx(allselected('Date'), 'Date'[Date])
var _stime = minx(allselected('Time'), 'Date'[Time])
var _etime = Maxx(allselected('Time'), 'Date'[Time])
var _st = _sdate + _stime
var _ed = _edate + _etime
var _start = max(Table[take off], _st)
var _end = min(Table[Land on], _ed)
return
calculate(sumx(Table, datediff(_start,_end,second)), filter( Table, (Table[take off] >= _st && Table[take off] <=ed) || (Table[Land on] >= _st && Table[Land on] <=ed) ))

I have re-written the measure to correct the error and works very well in matrix visual but it can't work with card visual as it gives me BLANK. 
Here is the measure: 

Time in Air =

var sdate = MINX(ALLSELECTED(CalendarDIM), CalendarDIM[Date])

var endate = MAXX(ALLSELECTED(CalendarDIM), CalendarDIM[Date]) + 1

var StartDate = MAX(MAX(Table[take off]), sdate)

var EndDate = MIN(MIN(Table[land on]), endate)

return CALCULATE( sumx(Table, DATEDIFF(StartDate, EndDate,MINUTE)) , FILTER(Table,

(Table[take off] >= StartDate && Table[take off] <= EndDate ) || (Table[land on] >= StartDate && Table[land on] <= EndDate )

 

Here is the result: 

 

I'll really appreciate if anyone can help me fix this. 
Thank you
