How to count Consecutive with duplicate date

[matus_jun]

Hi I want to know how to count 

From this picture
shift_date = date employee work
sum = worhing hour 8 is normal work time and 2 is overtime 
So I got duplicate shift_date 
group_id = Consecutive date 
Count_Column = count day Consecutive
In group_id = 1 ,I should get 6 
this is my dax for counting 

Count_Column = CALCULATE(COUNT(table[group_id]),FILTER(ALL('table'),table[employee_id]=EARLIER(table[employee_id])&&table[group_id]=EARLIER(table[group_id])))

I work fine without duplicate date
please help me to count same way with duplicate date 
Thank you alot and sorry for my english

@matus_jun , Try using Distinct

Count_Column =
CALCULATE(
COUNTROWS(
DISTINCT(
SELECTCOLUMNS(
FILTER(
ALL('table'),
'table'[employee_id] = EARLIER('table'[employee_id]) &&
'table'[group_id] = EARLIER('table'[group_id])
),
"shift_date", 'table'[shift_date]
)
)
)
)

EARLIER/EARLIEST refers to an earlier row context which doesn't exist. 
It show like this i dont understand how EARLIER work

I suggest, you transform the data in Power Query so that you will have to get rid of the duplicate records and two seperate columns one for Total Hours and one for OT, this way you will be to do your aggregations easily in Power BI
