PowerBI RANKX is not continious - powerbi

Question

I want to show the TOP10 difference in a measure.
The difference is calculated YTD actual + Rest of the year forecast - Full year budget values.
The normal measure looks like this:
VAR _Year =
SELECTEDVALUE ( 'Calendar'[Year] )
RETURN
(
CALCULATE (
SELECTEDMEASURE (),
DATESYTD ( Calendar[Dates] ),
CRDB[Scenario] = "Actual",
ALL ( CRDB[ForecastTypeFinal] )
)
+ CALCULATE (
SELECTEDMEASURE (),
CRDB[Scenario] = "Forecast",
'Calendar'[Dates] >= DATE ( _Year, 1, 1 )
&& 'Calendar'[Dates] <= DATE ( _Year, 12, 31 )
)
)
- CALCULATE (
SELECTEDMEASURE (),
Calendar[Dates] >= DATE ( _Year, 1, 1 )
&& Calendar[Dates] <= DATE ( _Year, 12, 31 ),
CRDB[Scenario] = "Budget",
ALL ( CRDB[ForecastTypeFinal] )
)
I would like to rank by project, so I made this ranking measure:
RANKX (
ALL ( CRDB[Project ID - Project ID Level 01 (Text)] ),
(
CALCULATE (
SELECTEDMEASURE (),
DATESYTD ( Calendar[Dates] ),
CRDB[Scenario] = "Actual",
ALL ( CRDB[ForecastTypeFinal] )
)
+ CALCULATE (
SELECTEDMEASURE (),
CRDB[Scenario] = "Forecast",
'Calendar'[Dates] >= DATE ( SELECTEDVALUE ( 'Calendar'[Year] ), 1, 1 )
&& 'Calendar'[Dates] <= DATE ( SELECTEDVALUE ( 'Calendar'[Year] ), 12, 31 )
)
)
- CALCULATE (
SELECTEDMEASURE (),
Calendar[Dates] >= DATE ( SELECTEDVALUE ( 'Calendar'[Year] ), 1, 1 )
&& Calendar[Dates] <= DATE ( SELECTEDVALUE ( 'Calendar'[Year] ), 12, 31 ),
CRDB[Scenario] = "Budget",
ALL ( CRDB[ForecastTypeFinal] )
),
,
DESC
))
The ranking gets me the correct projects, but when I look at the rank values, they are not right:
ranking values
The values are not the same, so it is no reason for skipping places.
What do I do wrong?
Thank you for your help in advance.
