When not using auto QRZ/HamQTH lookups, and later running Callbook > Update database, it seems it imports most data from either QRZ or HamQTH, but it does not import the grid locator. When viewing/editing a specific QSO, hitting F11 to update from callbook service, it does update the grid locator.

I've tried this with both QRZ (paid subscription) and HamQTH for callbook backend. The only configuration option I can find around this is under New QSO, 'Always overwrite info from previous QSO with callbook data' and 'Always overwrite only CQ, ITU zones, county and US state'. Neither option seems to make a difference.

Is there another method to import the grid locator for bulk records?
