Specified bank name was replaced by name from bank master record

What causes this issue?

When you enter a bank key, the bank name is always taken from the bank
master record. Making an entry is superfluous in this case. Any name
entered which differs with the name in the master record is
automatically cancelled by the system and replaced with the name in the
master record.

How to fix this error?

Only enter the name of the bank if you do not enter any other bank data
(bank number, account number, bank country).
