Please check individual value adjustment for current account

What causes this issue?

Check the IVA values stored on the account after the loss on
receivables has been posted.
If you have posted a loss on receivables using part of the IVA, for
example, and a fixed value is stored on the account as IVA, it is
possible that a new IVA addition would be determined during the next
valuation run.
Since you have several handling options from an organizational
perspective, it is advisable to maintain the IVA values individually.
