No parts after opening Altium files, but in the IPC-2581 export visible

Hi everyone,
actually I’m trying to import Altium PcbDoc files in the PCB Editor but when doing so, it doesn’t display some parts, mainly passive parts like resistors, etc. But when I export the converted PCB as an IPC-2581 file and open it in Viewer like ZOFZ then I see all parts. Looking at the IPC-2581 XML file tells the same. Do you have any Idea what’s the issue here? How can I display the passive parts?

Asking ChatGPT gives me the reason that the of my Altium parts doesn’t match the library of KiCAD, but as I’m new to KiCAD I don’t know to further check this information.

ChatGPT will have no clue.

Can you please report a bug with the files in question?
