Logging of a callsign that is not available on qrz.com

[hb9tsi]

Hello
I observed that when a callsign can not be found in qrz.com then the operator name and the grid locator is left blank although I already had a QSO with the same station earlier and the operator name and grid locator are captured in the log. Obviously log4OM2 is only taking information from external services but not from the log.
Sometimes the grid locator is outdated on qrz.com. Even when I have corrected the grid locator at an earlier QSO and the actual grid locator is in the log Log4OM2 shows again the old grid locator from qrz.com. Is there a possibility that Log4OM2 considers the log information prior to the information of external services?
