What causes this issue?

In your system, account numbers are used as interest calculation
indicators. (The indicator VZSKZ_L in the table T056 is set.) Some of
these account numbers will be converted. However, they will not be
converted in all company codes in which they are used at the moment.
To ensure that interest calculation works correctly after the
conversion, the old settings for the interest calculation indicators
must still be available after the conversion. In addition, the existing
settings for interest calculation must be copied to the new values.
