Not able to replace STL

[amoe83]

Hey there,
I am using OrcaSlicer and would like to update or add a STL file to an existing project.
But when I load the .3mf project with the old STL (Seitenteil Folienrollenhalter.stl) and right click on the model, the option 'Replace with STL' is grayed out (first attachment).

When I import (Ctrl+I) the additional STL file (Seitenteil Folienrollenhalter 01-2.stl), and right click on this model, the option 'Replace with STL' is normally available.
After importing the additional STL, it is loaded outside the old STL configurations, like Layer Heights and Generic Cylinders.
I would like to use the settings I already configured with new STLs and don´t know how to set it up in this slicer.
