Subprocess diagram empty in admin application

I have created a simple process with a collapsed subprocess.

From the workflow application, I can open the process diagram and open the subprocess diagram by clicking on the sub element.


When I try the same from the Flowable Admin application, the process diagram can be opened, but clicking on the sub element yields an empty diagram.

Is it possible to open a subprocess diagram in the admin application?

It’s 2025 and there is still no solution to this
