[Dx4win] How to force one QSO per QSL label in DX4WIN 9.0.9.1259?

[Berkin AYDOGMUS, TA3J]

Hello,

I am using DX4WIN version 9.0.9.1259 and I am trying to print QSL labels on
a custom 70 x 35 mm label sheet.

In the Custom Label Editor I have set Max QSOs = 1.

However, DX4WIN still prints two QSOs with the same DX station on one label.

For example, with FR5DX:

10-Dec-2000 QSO was made with my callsign TA3J
15-Aug-2004 QSO was made with my callsign TA3J/4

These QSOs must go on different QSL cards, so I need one QSO per label,
regardless of the DX station callsign.

I also tested Print Labels in Sequence, but DX4WIN still combined two QSOs
on the same label.

Is there a setting or known workaround in DX4WIN 9.0.9.1259 to force exactly
one QSO per QSL label?

Thank you very much for your help.
