Dynamic Calculation Based on Date

Hi Everyone, 
I am writing to ask question to the following problem: I am attempting to calculate deltas based on varying time intervals that are picked by the user with a slicer built on my M Date table . 
Data Tables:

1) Forecasted $ (contains data from 11/23/21 - 12/31/21)

2) Actual $ (contains data from 1/1/21 - 11/22/21)
3) Budget $ (contains data from 1/1/21 - 12/31/21)
4) M Date Table (M table showing all dates for 2019 - 2021). All tables are connected to M Date table through a date column. 
Calculations:
I need to calculate deltas based on 3 different time criterias:

1)Historical - example: (1/1/21 to 10/31/21) -> SUM(Actual $ [1/1/21,10/31/21] ) - SUM(Budget $ [1/1/21,10/31/21])
2)Historical + Future - example: (1/1/21 to 11/31/21) ->
(SUM(Actual $ [1/1/21,11/22/21]) + SUM(Forecast $ [11/23/21,11/31/21])) - SUM(Budget $ [1/1/21,11/31/21]) 
3) Future - example: (12/1/21 - 12/31/21) -> SUM(Forecasted $ [12/1/21,12/31/21]) - SUM(Budget $ [12/1/21, 12/31/21]) 
I can generate the proper results but when I choose different time intervals the measure breaks. On another note, the chart will show all dates from 2019-2021 even though only 2021 dates are selected and the filter shows that only 2021 dates are being used although 2019/2020 appear visually. 

The DAX Formula I used:

Calculation =

// Variables
VAR Cost_MinDate = MIN(Actual$ [Date])
VAR Cost_MaxDate = MAX(Actual$ [Date])
VAR Date_MinSlicer = MIN(MDate[Date])
VAR Date_MaxSlicer = MAX(MDate[Date])
VAR ACT_DATE_PLUS_ONE = Cost_MaxDate + 1

// Variable Calculations
VAR Variable1 =
(CALCULATE(SUM(Actual$[Dollars]),DATESBETWEEN(s_Date[Date],Date_MinSlicer,Cost_MaxDate))
+ CALCULATE(SUM(Forecast$[Dollars]),DATESBETWEEN(s_Date[Date],Cost_Date_Plus_One,Date_MaxSlicer)))

VAR Variable2 = CALCULATE(SUM(Actual$[Dollars]),DATESBETWEEN(s_Date[Date],Date_MinSlicer,Cost_MaxDate))

VAR Variable3 = CALCULATE(SUM(Forecast$[Dollars]),DATESBETWEEN(s_Date[Date],Date_MinSlicer,Date_MaxSlicer))

VAR Variable4 = CALCULATE(SUM(Budget$[Dollars),DATESBETWEEN(s_Date[Date],Date_MinSlicer,Date_MaxSlicer))
// Calculation
RETURN
SWITCH(

TRUE(),

AND(Cost_MinDate >= Date_MinSlicer, Date_MaxSlicer <= Cost_MaxDate),
(Variable2 - Variable4),
AND(Cost_MinDate >= Date_MinSlicer,Cost_MaxDate < Date_MaxSlicer),
(Variable1 - Variable4),
Cost_MaxDate < Date_MinSlicer,
(Variable3 - Variable4)
)

Thank you in advance for your help and time. This problem has been perplexing me for about 2 weeks now.
