Balance is not calculating correct ,if date filter is applied?

Question

I am retrieving Data between two date, but Balance is not calculating correct,

 

Below data with query.

Create table #tbl_Receivable (Rec_ID int,Customer_ID int,Rec_Date date,Rec_Amount varchar(50),Inv_type varchar(50));
  INSERT INTO #tbl_Receivable VALUES

  (111,1,'2020-03-06',5000,'Payable'),
  (112,1,'2020-03-07',2000,'Received'),
  (113,1,'2020-03-08',1000,'Payable'),
  (114,1,'2020-03-08',2000,'Payable'),
   (115,1,'2020-03-09',4000,'Received')
 ;
  with Q as
  (
      select Rec_ID, Customer_ID, '' as [ ], Rec_Date, Rec_Amount as Payable, 0 as Received
      from #tbl_Receivable
      where Inv_type = 'Payable'
      union all
      select Rec_ID, Customer_ID, '', Rec_Date, 0, Rec_Amount
      from #tbl_Receivable t1
      where Inv_type = 'Received'
      union all
      select 0, Customer_ID, 'Opening', DATEADD(d, -1, MIN(Rec_Date)), 0, 0
      from #tbl_Receivable
      group by Customer_ID
  )
  select Customer_ID, [ ], Rec_Date, Payable, Received, sum(Payable - Received) over (partition by Customer_ID order by Rec_Date, Rec_ID) as Balance
  from Q
 where Rec_Date between '2020-03-08' and '2020-03-09'
  order by Customer_ID, Rec_Date, Rec_ID
  Drop table #tbl_Receivable

 

Without Date Filter

Create table #tbl_Receivable (Rec_ID int,Customer_ID int,Rec_Date date,Rec_Amount varchar(50),Inv_type varchar(50));
  INSERT INTO #tbl_Receivable VALUES

 (111,1,'2020-03-06',5000,'Payable'),
 (112,1,'2020-03-07',2000,'Received'),
 (113,1,'2020-03-08',1000,'Payable'),
 (114,1,'2020-03-08',2000,'Payable'),
 (115,1,'2020-03-09',4000,'Received')
 ;
 with Q as
 (
 select Rec_ID, Customer_ID, '' as [ ], Rec_Date, Rec_Amount as Payable, 0 as Received
 from #tbl_Receivable
 where Inv_type = 'Payable'
 union all
 select Rec_ID, Customer_ID, '', Rec_Date, 0, Rec_Amount
 from #tbl_Receivable t1
 where Inv_type = 'Received'
 union all
 select 0, Customer_ID, 'Opening', DATEADD(d, -1, MIN(Rec_Date)), 0, 0
 from #tbl_Receivable
 group by Customer_ID
 )
 select Customer_ID, [ ], Rec_Date, Payable, Received, sum(Payable - Received) over (partition by Customer_ID order by Rec_Date, Rec_ID) as Balance
 from Q
 --where Rec_Date between '2020-03-08' and '2020-03-09'
  order by Customer_ID, Rec_Date, Rec_ID
 Drop table #tbl_Receivable

Ouput is

 

 

as You can see in 2020-03-07 Balance is 3000,
