LotW Upload

eddy on5jk

For the first time in years , this morning i had a problem uploading to LotW.
Add Requested fills the queue with 164 QSO’s. Then try to upload to LotW.
After putting my Password, i got the message: No QSO uploaded or processed, because 5 QSO’s are duplicates.
In the queue i do not find any duplicate.
How to proceed please?
