Advance Payment Record Removed When Deleting Applied Credit from Bill

Advance Payment Record Removed When Deleting Applied Credit from Bill

Hello,
So while working with vendor advance payments, I noticed that removing the applied credit from a bill also removes the corresponding entry from the Payments Made section.
What I did :
Recorded an advance payment to a vendor through Payments Made.
Created a vendor bill.
Applied the advance payment to the bill.
Opened the bill and went to the Credits Applied / Payments Made  section.
Clicked the delete icon for the applied credit/payment.

What I observed is,
After deleting the applied credit from the bill:
The credit/payment was removed from the bill and the corresponding payment entry was also removed from the Payments Made section.

The system behaves as if the advance payment record no longer exists once the applied credit is deleted from the bill.
(Also I am using free trial plan of Zoho Books)

Thankyou!
