Duplicate mode not working with BCN3D Stratos 1.5.2

[Jdj796]

Application version
The latest version of BCN3D Stratos, 1.5.2.

Platform
Operating system Windows 11.

Printer
BCN3D ellipse W50

Reproduction steps
Tried to use duplication mode with Stratos 1.5.1. Also tried on different computers. Windows 10 and 11. Did not work. Tried again to use duplication mode with Stratos 1.5.2. Did not work.

Actual results
First extruder is printing on 1.5.1 and the second extruder standstill. Second attempt was with 1.5.2 and the opposite happend. The second extruder is printing and the first extruder standstill.

Expected results
The build platform is devided in two sections in Stratos if the duplicate mode is used. First extruder settings are copied by the second extruder. Sliced the object and send to the printer.

Expected both extruders to print at the same time. It seems to be an software issue

What could be the solution?
