Hi Matej, thank you for your file.
I tested it and it looks I am able to import your region (I used original one and also changed the values for my project).
Can you check your Project and Output coordinate system settings?
Also, are the images from the attached picture georeferenced (because I don’t see any orange lines for the images)?
Can you try the application reset (Reset RealityCapture) and then try the import again?
