I think that the import of credit card transactions is not working correctly when the Payee Name is not already in KMyMoney. It appears that it is using the last known Payee Name instead of leaving it blank.
Here is a recent example:

<STMTTRN>
<TRNTYPE>PAYMENT
<DTPOSTED>20210806160000[0:UTC]
<TRNAMT>-1.07
<FITID>202108061
<CORRECTFITID>202108061
<CORRECTACTION>REPLACE
<NAME>Kindle Svcs*2P8C792O1 866-321-88
<MEMO>Kindle Svcs*2P8C792O1 866-321-88
</STMTTRN>

This imported with a Payee name of
Zelle Transfer Conf# T0BN438LM;
and there is no such a name anywhere in the file being imported.

Not good.
Is there a setting within KMyMoney to tell it to make it a blank or some such ?
Help !!!

thanks

I filed a bug and this suggestion solved my issue, though I still think its a bug.

One additional thought - please look at the payee info for "Zelle Transfer Conf# T0BN438LM" and see if it has matching enabled, and if anything in the new transaction happens to meet the matching criteria.
