miRack+Drambo not

please tell me why projects with miRack patches do not load if I use one of the racks for send effects, for example. an empty patch is constantly displayed. Why is there no saving as a full-fledged auv3 parameter file that should be completely registered inside the drumbo plugin. Even trying to create a separate patch save for the project does not help, the entire project is saved completely empty. and sometimes it opens. if I compiled a full-fledged drum rack from miRack in drumbo, I will lose everything ((( what are the solutions?
