New QSO's not recognized for upload to Club Log

[PA7CT]

I just logged 3 QSO's in RUMLogNG 5.6.8 (on MacOS 12.1 arm64) and uploaded them to LotW without issue. Next, I tried to upload them to Clublog as well and selected Logbook -> Upload new QSOs to Club Log, but no new QSO's where detected.

On a side note: it seems a bit confusing to me that uploading new QSO's to LotW or eQSL is in the QSL menu while it is in the Logbook menu for Clublog.
