Wrong TDS posting in F-54 -FICO

Dear Sir,

I am facing one peculiars issue while doing TDS, F-54 is not calculating Perfectly

I did Advance Payment: with F-48

29 - Sp. GL(A) -    Vendor Account Dr.     5000

50 Bank Outgoing Cr.     4900-

50 TDS Payable Cr.      100-

Then Invoice Booking: with FB60

40 Expense Account Dr.      8000

31 Vendor Account Cr.       7840-

50 TDS Payable Acc Cr.       160-

while Doing Advance Clearing (F-54) i Should get below entries

39 - Sp. GL(A) -     Vendor Account Cr.     5000

26 - Vendor Account Dr.     4900

40    TDS Payable Dr.     100

But I am getting following Entries

39 - Sp. GL(A) -      Vendor Account Cr.     5000

26 -                          Vendor Account Dr.    4840

40                             TDS Payable Dr.     160

In my case Invoice value getting reverse  but practically Advance payment should get reversed , Please Guide me in this regard.
