[Dx4win] LOTW issue

[PY2YP]

Hello

I wonder what am I missing regarding this LOTW issue:
I hold 4 callsigns: PY2YP, PY9UC, PR2O and ZZ2Z. The LOTW under the QSOs 
menu shows the following statistics:
PY2YP: 9,412 QSLs;
PY9UC: 17 QSLs;
PR2O: 1,100 QSLs;
ZZ2Z: 5,131 QSLs.
The total is: 15,660 QSLs

However the "Your QSOs" page shows:
You have 57,993 QSO records
You have 15,662 QSL records

Where are the missing 2 QSLs?
